I find it really nice and you can reach a good orgasm while doin it.
The best thing to do is to get some lube and smother your selfs in it(penis, arse)
it really does hurt the first time its just like having a poo for the boys its very tight and warm so ive been told, but will hurt alot if you dont use anything. Comdoms are good also they protect you from dicieses and stops poo getting on certain parts of the body.
You should be slow and ease it in, dont force you would expect a little blood sometimes.
While doin this position get your fella to touch your clit and boobs this will really turn you on.
Good luck let me know if you want to know owt else. Xz
