So me and my boyfriend decided to have sex when i spent the night at his house. The next morning it was just like a regular morning, your get up take a shower get dressed ETC. After all that is done he takes me home. A few hours later i get a call from him saying that he has a rash broke out on his penis. I looked at it after he put some type of cream on. What cream I don’t know. But it was just on his penis it wasn’t on the head it was just on the “body” of the penis. He claims that it is an std. I say otherwise. So does anybody know what this can mean? Is it an std or some sort of irritation? Please help!
