if this is an innocent skin cyst on the shaft of your penis and properly diagnosed by a medical professional (and not self-diagnosed) a cyst would not preclude you from sexual activity as long as its presence did not worry your partner. these tiny cysts (often sebaceous cysts) can be easily removed so if they are concerning you just get the cyst taken off. as long as you are sure it is a cyst and not an std. then it should be no problem. hopefully it won't freak your partner out though. you could try using one of those penis health cremes (man1 man oil is a good one) to improve upon overall skin texture and hygiene down there. this might counterbalance the issue with the cyst. hope this helps!
is it ok to have sex with a cyst on your penis? . i am wondering if having a cyst on my penis will stop me from having sex and i am worried about my sex life. so i am asking this question out of curiosity and worry. its a very small cyst on the lower bottom side of my shaft.
