I always use protection during sex and haven't changed any shower gels or anything.
I have started a relationship with someone and foolishly , we have yet to be both sexually tested. we started having unprotected sex about 3 weeks ago. yesterday the end of my penis is red and itchy and I'm not sure why.it has one or two very small cut like ridges in it. this has never happened before.
any information would be good, cheers
