Erectile Changes
Shifts in how erections are experienced can occur after cancer due to changes in nerves, blood flow, or hormones. Learn what causes it and what treatment options may help.
Changes in erections are common during and after cancer treatment
While erections, pleasure, and orgasm may feel different, intimacy and satisfying sexual experiences are still possible.
Erections are triggered by arousal—physical or mental.
- Signals travel through nerves near the prostate
- Blood flows into the penis, making it firm
- The penis fills like a sponge with blood
After cancer treatment:
- Surgery or radiation can affect these nerves
- Nerves may recover slowly (months to ~2 years)
- Some changes may be longer-lasting
Even if erections change, pleasure is still possible.
If erection changes are ongoing or distressing, and you would really like to focus on improving erections, there are erection treatment options available.
These may include:
- Medications to support erections
- Vacuum devices
- Injections
- External Penis Prosthesis (and resources for products)
- Inflatable penile prosthetic (surgery) options
You deserve support. If this is affecting your quality of life or relationships, a healthcare provider can help you explore your options.
A different way to think about erections
After cancer treatment, erections may happen more in response to touch rather than spontaneously or just when thinking sexual thoughts. More stimulation and sensation may be needed to get an erection going. This is a normal shift.
For some men, now might not be the right time, or they may not have a lot of motivation to focus on sexuality, or sexual pleasure. Perhaps they don’t have a partner and don’t have a lot of opportunity OR maybe they don’t want to try to have sex with all the different treatment options. They may prefer to wait until their natural erections come back. But if they just wait and don’t do anything to try and help the erection recovery process along, they miss out on an important opportunity to promote penile recovery and this can result in reduced penile function.
Some men may also be interested in doing everything they can to preserve their erectile function for the future, or to promote their recovery so that erections come back sooner. They may be interested in penile rehabilitation.
Increasing blood flow to the penis (including through touch or masturbation) can help support tissue health. Whether the goal is for sexual pleasure or more for blood flow - for more information see: penile rehabilitation
Intimacy Without a Firm Erection
Intimacy may look different after cancer — and that’s okay.
Intimacy is not only about erections or intercourse. It can include many forms of connection, pleasure, and closeness.
Exploring what feels good now is part of adapting over time.
❤️ Physical touch and closeness
Holding hands, cuddling, kissing, and skin-to-skin contact.
❤️ Sexual touch without penetration
Exploring touch, stimulation, and pleasure in different ways.
❤️ Oral sex or other stimulation
Intimacy does not have to look one specific way to be meaningful.
❤️ Toys or external aids
Tools can support pleasure and exploration.
❤️ Emotional intimacy
Talking, laughing, sharing closeness, and feeling connected.
Pleasure, Orgasm & Ejaculation
These are separate processes—not all-or-nothing.
Even if erections change, pleasure and orgasm may still be possible.
These experiences are separate. You can experience pleasure without an erection, have an orgasm without ejaculating, feel intimacy and connection in many different ways.
Sensation Changes
Things may feel:
- less intense
- delayed
- unfamiliar
What worked before may feel different now.
Orgasm Changes
Orgasm may:
- take longer
- feel different
- require more stimulation
It is often still possible.
Stimulation & Touch
Some people benefit from:
- stronger stimulation
- vibrators or toys
- lubricant
- non-penetrative touch
Mental Arousal
Mental focus may play a bigger role.
Fantasy, erotic material, relaxation, and reducing distraction may help.
💡 Ways to Explore and Adapt
If erections have changed, these ideas may help you reconnect with pleasure and intimacy:
- Try new types of touch or stimulation (it can take time to find what works)
- Talk openly with your partner about what feels good
- Focus on pleasure rather than trying to get to orgasm
- Use a lubricant to increase comfort and reduce friction - stimulation may take longer than it did before
- Consider sex toys such as vibrators to support stimulation - this is good if you need more intensity
- Explore thinking about sexual fantasies or memories, or reading or viewing erotic material as ways to enhance arousal
- Try masturbation (alone or with a partner) to learn what your body responds to now
"I was disappointed that what used to work for me (receiving oral sex from my partner) didn’t seem to work for me to have an orgasm anymore. I talked to my partner about what other options they would be willing to try in order to try to increase my sensation. We decided together that we would try a hand-held vibrator. We also decided to use a water-based lubricant. We took our time and I found when I wasn’t rushed, and when my partner used the vibrator, that they didn’t tire as quickly. The intensity of the vibration seemed to be just what I needed to get me across that threshold to orgasm. The vibrator helped me feel much more pleasure and stimulation, without feeling bad that it was taking too long for more partner."
