After having sex on Friday evening I have been having some slight penis irritation. A sort of tingling feeling in the head? It doesn't burn when I urinate, theres no discharge or broken skin or blisters. I also feel like having a wee more often but when I go its nothing more than a dribble! Up untill a week a go I was a virgin and so was my girlfriend. I've never noticed this when I have masterbated before. Theres no signs of STDs so I'm just wondering whether it could be something irritating my skin from the condom? The lube? There is no spermicide on the condom. Or the fact I'd never penetrated anyone till last week. I used to masterbate a lot and this caused a friction burn to appear on my foreskin, but everything else looks normal!
