After sex with my girlfriend last week, I found that my foreskin in the area just below the glans was very red and torn. It was only the next day that it was very sore and tender, though it healed up really quick (two days). I've had "friction burns" many times in my youth from vigorous sex, LOL, but this was new to me. My gf had a hysterectomy last year, and as a result her natural lubrication can take quite a while to get going, so initially I assumed that was the problem. But now I have noticed that there are still some tiny tears in the skin, even after masturbating, almost as though the skin is just splitting rather than tearing. There's no other obvious signs of infection, such as redness or swelling, but I'm sure that some form of infection must be involved as the onset was so sudden.
I've looked around many forums such as here, and seen similar queries but any replies no matter how well intentioned, always seem to be very vague and so don't really help much.
So my question is, have any of the guys here (or any medical professionals), seen symptoms such as mine and successfully treated them? If so, could you tell me about your own experience and what worked for you?
I'm finding this all rather worrying, as most guys do when there's any sign of a problem with their "pride and joy". :) Thanks in advance...
