I made the comment today, "I don't know why guys don't like getting fucked in the ass." I had a mind blowing orgasm; I'm sure I lost brain cells during that one.
How does it feel? There's lots of different feelings. I feel vulerable offering my ass to another guy. Feeling his cock head against my hole is a thrill. There's some pain involved in getting his cock in all the way. Once everything is feeling good, it's mighty awesome. However, when I get a gritty feeling in my ass, I know I've got a poop problem and need to stop and deal with it.
I love feeling his big cock up my ass.
Here's some more thoughts:
I'm not really into doing a dude, but I like getting done! As far how to go about it, poop first, then use lots of lube (Astroglide gel works well for me), use condoms, work lube up into your ass, get his cock lubed up, a little more lube for you, then SLOWLY work his cock up your ass. I like to have my guy sitting on the edge of the bed or a chair, I've got my back to him and I lower my ass over his cock - I can control the penetration. Once everything is feeling good, we can switch positions and he can fuck me till we cum! You'll have to figure out works best for you after the initial penetration.
