Thanks for the info,
we tried full anal sex the last night, and although it hurt at first, we took things very slow, used loads of lube and our key thing, we communicated, i told Him when it became uncomfortable, and we slowed things down. After a while it started to feel good, especially when He started playing with my clit. Personally i think most of the discomfort is a mental thing, once you get over that, it shouldn't hurt that much.
