Trans men have sex in many of the same ways anyone else does, including oral sex, penetrative sex, mutual masturbation, and other forms of touch. What varies from person to person is anatomy, comfort level, whether someone has had surgery or taken hormones, and personal preference. There’s no single way trans men experience sex, but there are common themes worth understanding.
How Testosterone Changes Sex Drive and Anatomy
Most trans men who start testosterone notice a shift in libido fairly quickly. Sex drive often increases, sometimes dramatically, in the first weeks to months. Alongside that, the clitoris begins to grow in response to testosterone, a process sometimes called “bottom growth.” This growth is permanent and continues over months or years. The enlarged clitoris can become more sensitive to touch and more prominent when aroused, which changes how stimulation feels and what kinds of contact are pleasurable.
These changes mean that even without any surgery, a trans man’s body on testosterone responds differently during sex than it did before. Some trans men find bottom growth opens up new options for stimulation, including stroking or oral sex focused on the growth itself. Others may find their preferences stay roughly the same but the intensity changes.
Vaginal Dryness and Physical Comfort
One common side effect of testosterone that directly affects sex is vaginal atrophy. With less estrogen circulating, the vaginal lining becomes thinner, less stretchy, and produces less natural lubrication. The vaginal canal can also narrow. This can cause burning, itching, irritation, or pain during penetrative sex.
Using a generous amount of lubricant helps significantly. Some trans men also use a localized estrogen treatment, such as a small vaginal tablet or a low-dose ring, to restore moisture and tissue flexibility without affecting masculinization. These are applied directly to the tissue and release very small amounts of estrogen locally. If frontal penetration is part of your sex life and you’re experiencing discomfort, this is a solvable problem rather than something to push through.
Sex Without Surgery
Many trans men have fulfilling sex lives without any surgical procedures. Common sexual activities include oral sex, manual stimulation, grinding, mutual masturbation, and penetrative sex (either receiving vaginally or anally, or penetrating a partner using a strap-on). A strap-on typically involves a harness worn around the hips with an attached dildo, and harnesses come in a wide range of styles and sizes, including options designed for beginners and for larger bodies.
Strokers are another category of product designed for trans men. These are sleeves that fit over the enlarged clitoris and shaft area, providing sensation through a stroking motion. Some vibrate, some don’t. Pumps designed for bottom growth can temporarily increase engorgement and sensitivity before or during sex.
For trans men who want the experience of having a visible bulge or a more seamless transition into sex, prosthetic packers serve a dual purpose. Some are designed purely for daily wear, while “pack and play” models can be used both as everyday packers and during sex.
Sex After Bottom Surgery
Trans men who pursue bottom surgery generally choose between two procedures, each with different implications for sex.
Metoidioplasty
Metoidioplasty works with existing bottom growth by releasing the enlarged clitoris from surrounding tissue, creating a small phallus. Sensation is excellent: studies report that 89% to 100% of people retain full sensation after the procedure. The tradeoff is size. Most studies find that only 0% to 24% of people who’ve had a standard metoidioplasty are able to penetrate a partner, though a newer lengthening technique has shown more promising results, with about 81% of participants in one small study achieving penetrative sex. For many, the inability to penetrate is the most frustrating aspect of the surgery. Others prioritize sensation and a natural appearance over penetrative ability and find the results satisfying.
Phalloplasty
Phalloplasty constructs a full-sized penis, typically using tissue from the forearm or thigh. Forearm tissue tends to provide better sensation and cosmetic results. The new penis can develop both tactile and erotic sensation over time as nerves heal, though this process takes months to years. Because the constructed penis doesn’t contain erectile tissue, achieving an erection requires a penile implant, which is a small device placed inside the shaft during a later surgical stage. With the implant, penetrative sex becomes possible.
Both surgeries involve significant recovery time and multiple stages, and sexual activity resumes gradually. The experience of sex after either procedure varies widely from person to person.
Navigating Dysphoria During Sex
Gender dysphoria, the distress that comes from a mismatch between your body and your gender identity, doesn’t always disappear during intimacy. For some trans men, certain body parts, positions, or words can trigger discomfort even when they’re otherwise enjoying themselves. This is normal and doesn’t mean something is wrong.
Language matters more in bed than people often realize. Many trans men prefer specific terms for their body parts. Someone might use “chest” instead of “breasts,” or have a preferred word for their genitals. Asking what terms feel right, and using them consistently, creates a sense of safety that makes intimacy easier. This applies to partners of any gender.
Some trans men wear clothing during sex that helps them feel more at home in their body. Binding the chest, wearing a shirt, or using a harness or prosthetic can all reduce dysphoria and increase pleasure. Others find that certain sexual acts feel more affirming than others. There’s no formula here. What matters is identifying what feels good and communicating that clearly. A partner who treats these preferences as a normal part of sex, rather than something to question or work around, makes a significant difference.
Pregnancy Risk and Contraception
Testosterone is not birth control. Although it can suppress ovulation and stop periods in many people, it has never been studied or approved as a contraceptive. Pregnancies have occurred in trans men on testosterone. If you have a uterus, are having sex that involves sperm, and don’t want to become pregnant, you need a separate method of contraception. This is especially important because testosterone can cause harm to a developing fetus, including affecting genital and reproductive development.
Barrier methods like condoms, hormonal IUDs, copper IUDs, and other standard contraceptive options all remain available to trans men. An IUD is a popular choice because it works locally and doesn’t require remembering a daily pill.
STI Screening Based on Anatomy
STI risk depends on what body parts you have and what kinds of sex you’re having, not on gender identity alone. If you have a cervix, routine screening for chlamydia and gonorrhea applies to you the same way it does for anyone with a cervix, including annual screening if you’re under 25 or at higher risk. Cervical cancer screening (Pap smears) also follows standard guidelines for anyone who has a cervix, regardless of testosterone use or gender presentation.
If you’ve had metoidioplasty with urethral lengthening but still have a cervix, a urine test alone won’t catch cervical infections. A swab is needed. This is a detail worth knowing so you can advocate for the right test at a clinic visit. For anal sex, rectal STI screening is relevant regardless of what other anatomy you have. The key principle is straightforward: get screened based on the body parts involved in the sex you’re actually having.
