Me and my girlfriend have been dating for a little over 2 months now and we have yet to have sexual intercourse. We're not like your average 2month couple. We stay together at each others house every night. I've slept with her every night this month, except these two nights. At times, just like these it is very frustrating. I've been sexually active for over 4 years now with around 7 different females. And she is a virgin. So, going from sex at least twice a month with no strings attached to a serious relationship with no sex at all, sometimes makes me want to have a mental breakdown.

I'm 19 and have been with my girlfriend for almost three years, except a couple months break last year when I broke up with her for fear of commitment. She's a year younger than me, and prior to our relationship, she had done some oral sex and handjobs with two guys. I've never been sexually active with anyone other than her. We were both each other's first sexual intercourse partner. During our break apart last year, she had sex with another guy. Long story short, I love my girlfriend tons. I recently got a new job and we moved across the country together and now have an apartment. We're very happy together and have what I would consider a very healthy relationship.

In the back of my head, though, I am always jealous of her sexual history. She's been with 3 other guys, and I've never even seen another girl naked in person. I've seen figures that men typically have around 8 sexual partners in their lifetimes. I feel horrible for thinking this, but it really bothers me that if I stay with my girlfriend (which I want to -- I really feel that I could be with her forever), I'll never have sex with another girl, because I have my morals, and I could never cheat on anyone. I'm not even sure what I'm asking, but do you have any advice for guys (or girls) in my situation?

I'm so used to seeing TV shows with the "bachelor" who constantly sleeps around and never has a partner, or the one who's looking for "the one" and falls in love and looses someone new every five episodes. And at school, I'm used to everyone dating for a week, then more or less switching partners, or randomly sleeping together.

My question is: How many partners do most people have in their life time? And do one-week stands count as a small relationship? How short can a relationship be, and how long can it before moving on and finding someone new becomes really hard? Can people be in committed, loving, polygamous relationships, or have different partners for different things (like someone else for especially rough sex you wouldn't want to subject a gentler emotional-lover to)?

I have no reservations when I have casual sex. However when one of these flings turns into a relationship and things get serious I don't want to have sex with them anymore. It has happened with my last three boyfriends and has been the primary reason for my breakups. It feels like a normal relationship...we are best friends, we do almost everything together, I care about him tremendously, but I get scared when he wants to have sex. Why can I only have emotionally detached sex?
