๐Ÿ˜•๐Ÿ˜• his itch is making me paranoid

EVERYTIME me and my boyfriend have sex, afterwards he gets EXTREMELY itchy around his bits. I mean like, EXTREMELY itchy. Where he actually nearly takes the skin of himself. He dosent say anything to me about it, and he still loves having sex with me. We've been together 2 years. I've asked him, is that only when you have sex with me and he's said yea. I've been tested and that, and I'm clean and fine, and I don't itch. It makes me think all the love juices drying up on him after might be the cause. (I get extremely wet) he's never had sex with anyone who gets as wet as me. He said. I know it hasn't put him off me or anything, but I do get overly paranoid. What could it be? Anyone else's man itch a lot.?ย
