My girlfriend jiggles like crazy during sex! I can't seem to control her! One night she jiggled right off the bed! Please help.

I haven't really been able to talk to any girls since my breakup with my ex-wife 6 months ago. We haven't really signed any divorce papers, so I feel very obligated to stay faithful to her even though our relationship as we know it is over and done with. Will I still have this problem even when we actually get divorced? And will I forever feel bad about making the first move to end this relationship? Because for the past three months I could neither sleep or concentrate on my studies. My commitment to her and my love for her was the only thing that helped me to go on with my life. Now that's over I am totally lost. Please help me with my problem.

My girlfriend and I have great sex, but lately she has been asking me to talk dirty to her. The problem with this is that I thought I'd already been doing this. I don't know what to say, literally. Any hints on what I might be able to say to her? I already talk kind of dirty to her, but she wants it nasty. What do I say?

How would I go about asking a partner about his past?

I'm in a long distance relationship and my boyfriend always wants to try "sexting" or have "phone sex." I'm just not comfortable doing so, and don't even know how. Any pointers?

My (ex?) best friend and I drifted apart a few months ago because of her new boyfriend and my busy schedule. Before, we were like sisters, but now we just ignore each other. She's recently been trying to contact me, and even though I do miss her more than anything, I haven't been answering her calls. I'm not sure if I want her back in my life. There were certain things about our friendship that didn't seem right. There were things we couldn't/wouldn't tell each other. She also liked to make me feel unimportant. I know this makes it seem like we never were true friends, but we meant everything to each other. I just don't know if I should let her back in or not? Please help?
