Let me start off by saying I have a very scant sex life. Last night I was with a girl for the first time in a number of months. We tried intercourse, but for some reason she was unable to 'open' up enough for me to enter, so instead, she started to use her hand. At one point she was pulling rather strongly and I think she had 2 small rings on her finger. Before I knew it I was having some very sharp burning pain on the upper right side of the glans. There was no visible wound or redness or swelling of any kind, yet the slightest feather touch causes pain now. I thought perhaps it would subside but it has not and I am reading in various places that depending on the cause this may need medical intervention of sorts? Anyway, The hardest part is walking and I've had to just bear it, in the hope that it will subside sooner or later. The thing is, if I put pressure on it, it does not hurt. Only very gentle touching causes a burning pain in that spot. What can this be and what should I do about it?
