I'm a 19-year old homosexual male who has always struggled with his sexual health. Put simply, I physically do not experience much pleasure when masturbating or taking part in sex. I feel pleasure in my penis in the immediate 10-15 seconds before and during orgasm, but I very rarely experience anything before that. In addition, over the last year or so my penis has often shown signs of balanitis (it becomes sore, itchy, the foreskin sometimes becomes red and there is usually a build-up of smegma) 12-48 hours after sexual activity, usually after masturbating for more than 3 or 4 times a week. My personal hygiene is otherwise excellent, so I'm wondering if this is instead a secondary effect of my lack of pleasure when having sex. I would say I have a lower sex drive than the average male my age. I've not been able to find out what's wrong with me yet so it would significantly boost my confidence and self-esteem if I at least knew what the issue is. Thanks in advance!
