yeah, lots of lube helps, my ex said it hurts her to start with so i have to take it slowly, but then i am 7 1/2" which didn't help, but after lots of play it goes in quite nicely then she really enjoys it, she's certainly louder than regular sex.
my ex-ex though was a different kettle of fish, she didn't even need any lube to fuck her in the ass, she was able to take a whole fist with a small amount of lube but i guess she must have been used to stuff like that from her previous boyfriend who was twice her age, (was 19 when i was with her). :shock:
