This Popped Up after 3 days what is it ?

Me and My boyfriend recently had sex and these popped up 3 days later . I’ve never had an STD ever in my life . HELP !! what is this ?

Hi, the pic is not clear enough

yikes. those look like blisters or cold sores. i would go get that looked at asap!!

Agree - looks like an ulcer. Could still be nothing to worry about though, id be checked regardless if there is no change…

After looking my boyfriend has the same thing on the shaft of his penis which is healing . He claims it to be a yeast infection . Could that be what it is ?
