Help. Has this happened to you?

So I'm a squirter, and during sex I squirt a lot. So after we're done, the beds a mess, he's very wet, you get the point. So last night after sex we showered and changed the sheets. But the skin above is penis had this weird rash, as if he broke out. 
Hasn't happened before, and I was wondering if this has happened to any of you, and what you did to stop it. Maybe it was something I ate. He thinks maybe bc of the moisture and having sex that, that might be why. I really don't want him to breakout every time we have sex. Help.
