Small red bumps on penis

Hello everyone. I have no choice but to reach out to the internet at this point. I have seen several different doctors including my mother who is a very good dermatologist and nobody can give me an answer as to what this is. I get small red bumps on my penis normally after sex and they last for a few days. I have had unprotected sex with over 50 women and none of them have told me they have caughten any stds from me. Hoping someone here can diagnose or give me an answer as to what these small bumps are. They are the size of the tip of a needle and are painless. if anyone has any idea what these may be please respond to this. Thank you so muchimage

Do you always use some form of Lube for sex?

i never use any form of lubricant when I have sex

This is most likely to have a simple explanation rather than something complex that the different Doctors you have seen and your mother are unable to explain. This is, the skin of the head of your penis is becoming irritated and something like the sebaceous glands on the head of your penis are responding in this manner …

thanks for the ease of mind honestly
