maybe you need to tell him what you like and what feels good, etc... obviously he is doing something different. If you can help him out, I'm sure it would be better for both of you.

i agree. if he does something while having sex that you like, tell him and he'll be bound to do it again. and if he doesnt do anything you like then suggest something to him that you would like.

There's nothing wrong with you. You two might just not connect in that way. You can have some of the most amazing sex with someone you don't like AT ALL. Sexual attraction and sexual energy compatibility often have nothing to do with emotional compatibility. I had a relationship like yours (ended up marrying him).

What you need to ask yourself is this: Is it worth it? Is the lack of sexual and physical fulfillment worth what you get from the relationship otherwise? Is the lack of it going to cause you problems in the future, like looking at other guys and maybe even cheating? Is staying with him (unless you have an open relationship) worth never having a different sexual partner?

Try exploring different things with him. Is the technique wrong? What about the environment? Does he make you feel sexy? Does he make you feel wanted? Does he TELL you how much he wants you or enjoys you? Consider getting some books for you to read together, or if you REALLY want to stick with him, see a sex counselor.

You can't fake the natural sudden connection people have, but you can learn to be an excellent lover. You two already have the foundation layed out to have the best sex of your lives... an excellent emotional relationship. I promise you, the best sex you will ever have is with someone you truly connect with like that, someone you love, trust with your whole life and everything in it, someone who makes you feel safe, and someone who really knows you.

Although suggestions will help, it sounds like you want serious improvement and not slight changes.
I'd recommend getting him to agree to an 'experiment week' with you. (Telling him outright that he's not good in bed will break a guy's heart...don't lie to him, but let him know that you're not really focused on/fulfilled by sex, and want to see if you can improve it).
This will really only work if you two are very candid and not at all shy of asking for what you want.

obviously don't tell him that ur not enjoying it BUT try new things & talk with him about changing things up a bit. maybe if u try new positions & whatnot, u'll find things that work for u.

question...was he a virgin when he met u???

Tell him about this. Let him know that you aren't comfortable in sex just yet, and maybe spend more time really,really getting to know him.

Also don't worry, there's nothing wrong with you. That's just not the way you two really mind meld.

get a vibrator maybe???

It's not uncommon for females to be unable to orgasm through intercourse alone. You may need to do a little self-servicing during intercourse to achieve orgasm. And there's nothing wrong with that.

i would tell him that you could lay back on the sex, or tell him that you aren't really enjoying the sex

If you love this guy ALOT and have gotten off with other guys, WHY would you think its YOU? it's probably him.
switch things up a bit. read some "Cosmo," get some sexy fun tips and bring something fun to the bedroom.

It's sometimes hard to talk about sex but after putting up and shutting up with some guys, I decided enough was enough and just came right out with it. "I like... and it feels good when you..." Focus on any positives and reinforce them non-confrontationally. Ask him what he likes, get comfortable with each other, explore each other. It's only a matter of time :)

have you ever enjoyed sex with him? as a woman on anti-depressants, I can tell you that any pills you take could affect not just your ability to orgasm but also to just *enjoy* sex. If that's not an issue, then I would say you guys need to experiment with things that turn *you* on... figure out what *you* like and try to integrate that into your sex life. but never tell him you don't feel excited having sex with him (or any variation of that). Guys have egos more fragile than eggshells.
