I had protected sex with a csw. Both the oral and vaginal were protected. I was not that into it so during the intercourse, I became a little soft not all the way though. I noticed that as this happened the condom was not as tight so it went up a little. I immediately pulled it down and continued. It just rose a little bur it never came fully off and I removed it and did not ejaculate from this encounter. I just removed the condom and stopped and put my clothes on and left. My concern is that my penis itched a lot immediately after but went away on its own. I've noticed that sometimes when I masturbate without much excitement it can itch very similarly as well. I'm an uncircumcised straight male. Any input is appreciated.
You had protected but there would be a risk for herpes and syphilis. Testing usually is only recommended if you have a regular partner.
