Probably too late to say by now but don't try to get his penis in your pee hole - the hole is quite delicate and isn't big enough It would be dangerous and you could get infections. I am told there is a porn website where someone does it but almost everything gets done by someone, however crazy.

However penetrating the pee hole feels very intense. You can do it with something small and very smooth so long as it is very clean and you clean yourself down there and are really careful. Use KY jelly, not spit to lubricate. Even so you still might get a peehole infection (cystitis) and have to take antibiotics. However I've done it for years (since I was 15) when I play with myself. Not most of the time but regularly. I can get a finger right inside now. The bladder entrance is about 4cm in. You have to relax that to go right in, like when you pee. To start with you get a burning sensation afterwards when you pee from the friction, so be very gentle. I like being submissive and I am rather kinky but I've not risked it with a boyfriend yet.

I'm not recommending it though, it is probably a bit dangerous and it is embarrassing to have to go to the doctor with an infection in there. (I had to do that.)

Just saw this when I Googled pee hole sex.
