so yesterday i had sex with my partner and we always have safe sex but we both had just gotten out the shower and playing with each other in there. we got out and went to the bed and his tip had went in just for a few seconds not long at all and i keep thinking the worse about if he had any precum on the tip but we showered and he was turned on in there so i was thinking it had washed off or wiped off by the time all that happened. i am an over thinker i just need reassurance lol. he told me i should be fine but just incase to take a plan b. what should i do?? am i fine?
