Dear Lovehacker, I've just turned 20 and I'm still a virgin and I've never had a serious boyfriend. Two of my bi guy friends and I have sometimes joked about having a threesome and I'm starting to consider it, just to get it over with. Is this a bad idea? Thanks, Third Wheel.

Dear Lovehacker, What is the best course of action when a colleague confesses their love to you? I'm not interested in them in that way and just don't feel the attraction. But I still have to work with them. Help!

Dear Lovehacker, I have been with my boyfriend for years and the sex isn't very enjoyable. I can't really orgasm from penetration alone -- I usually have to touch myself or use a vibrator afterwards. The main problem is that my boyfriend doesn't like going down on me. He's happy for me to give him oral sex though. I'm really not sure what to do about this.

Dear Lovehacker, My girlfriend and I have been together for a few years and we're really happy. But for the past six months or so she hasn't been orgasming very often during sex and only when I'm rubbing her clitoris. I know that changing up routines can be helpful for long term couples, but she's sexually very shy and only really interested in the missionary position. What should I do?

Dear Lovehacker, I moved cities late last year and my old boss is going to be in town for a visit soon. He suggested that we catch up but my only availability was during the evening. I didn't even think that it could be a problem until after we arranged to have dinner. He has a wife and I'm not sure if I should be worried about what she would think, especially because I'm single. Am I just being paranoid or is there something a bit off about having dinner alone with a married man? Thanks, B.
