A Previously Tight Frenum...
I used to have a tight frenum, I couldn't even retract when flaccid. And attempting to pull just a bit when erect was painful. Suprisingly (for me!); first time sex wasn't really painful. Initial penetration (horrible phrase XD) was a bit sore (her first time too, mindyou), but it was fine after that.
Since then my frenum seems to stretch a lot more. It happily retracts when flaccid, and can go all the way when it's in that just-nearly-"throbbing"-erect (sorry to be a gross-out, but you know there's different types of erect!). I think during sex the condom lube helps a lot.
Anyway! Recently whilst being fellated (hahaha, you do say to use proper terms - I got a post edited once for that) my foreskin started to really hurt. A kinda dull throbbing ow.
It turned out that my foreskin had kind of rolled in on itself, and stuck together - my frenum was coming out the middle of this. It took a few minutes of prodding in the bathroom for me to be able to (painfully @.@) sort this.
So! Any idea what happened, and has it happened to anyone else? Should I still be considering visiting the doctor over my frenum? I'd naturally rather not, as it works fine - but this was a new problem I'd not encountered before.
