Little painful red blister on penis

Those blisters appeared I think 3 or 4 days ago and they were more bumpy than they are not (seems like it bursted) They used to be more whiteish or my skin color. It was more of a blister and now just looks like a cut like you guys can see.

What is this? It appeared almost right away after I had intercourse. Probably the next day.

Will try to post picture

might be a fungal infection would have to see pictures in order to try to help to determine
