Back Door Love & Staying Up!?

Question

Ok, my girl friend says she has the best orgasms when I screw her a_s_s. Usually she wants me to do it after we have made love a couple of times already. My problem is that although I can get it up again it's not as hard as my original erection so entering her her becomes an issue. I try to do it with my first erection but she isn't in to it until we've already been at it for a while. She says she like to work up to it which is fine. Any suggestions for a longer harder erection even after having two or three orgasms myself already??

Answer 1

just have her suck on it till it's rock hard again.....

Answer 2

or pleasure her with a toy or something else first then having your when you go for her rear
