Am i screwed? i married a woman, and have never been with anyone else.

I guess the real question is; do you love your wife and would you like to stay with her? If she is a good friend, a good homemaker and someone you care for a great deal, you will most likely regret screwing up your marriage for a bit of strange.
Because in truth, you are going to find out once again, it isn't the equipment, but how the craftswoman uses it. There is NOTHING your wife cannot do or learn to do that any other woman can do. NOTHING.
So if you are happy, except for the natural desire to spread your seed, you may be a lot better off now than you will be if you give in to your lust.

Talk about sexual fantasies with her, such as making love in a shower, or by a fireplace. It is much better to work with what you have got, than leave her for an uncertain future.

If you feel that strongly then end things with her now before you sleep with someone behind her back.
Cheating would be a cunt move when you know you're going to do it well in advance...

If your current girlfriend is a good person & partner you might come to regret the decision to leave her but at least you would have only fucked things up for yourself

Scientific studies lol.

I think it's more of a personal issue than you want to accept. Plenty of married couples who waited have happy marriages. Not saying that's the right thing to do, but it used to be more of the norm and still isn't unheard of. Your sex life with your life is probably a little stale after all this time, or maybe you are just growing apart. It happens if you let it. Or maybe you just married the wrong person to begin with since you did marry for sex.

I think you need to start appreciating what you've got and stop fixating on these "scientific studies" etc etc that are telling you that you are most definitely going to cheat. I can tell you this, I have only slept with my husband. We met when we were 18 and chose to stay together get married, have kids etc. I'd be lying if I said I never thought about what it would be like to sleep with different guys. But, I love my husband so much that I would never ever imagine actually getting to a point where I'd be pursuing other men. That being said, I do watch porn and get my fill of different sexual scenarios/partners that way. One thing I can say about having one exclusive sex partner, our sex has gotten better and better over the years. Being in a close relationship with someone means you can be honest about everything, sexual fantasies, wants, needs. My husband and I are so great at pleasing each other, much better than any guy I could pick up off the street to fulfill my desire for "what am I missing out on". My advice, stick with it, you'll be having the most amazing sex if you do.

You could discuss it with her.....or just cheat and be very berry careful that you don't get caught.

Personally my partner would let me sleep with other men if we discussed it and agreed its the best thing for the relationship. I know this for a fact btw... i'm not just saying that

See a counselor and work through the issues.

If you want to leave, tell her. It wouldnt be fair if you cheated..

thats something to be proud of

So you would leave your wife just to screw some strange brods? Believe me, it's not as great as it sounds. I'd rather have someone who actually gives a damn about me than hookup with some skanks. But the bigger question is if you even love your wife at all. If you don't, then by all means, don't stay in a miserable relationship. Otherwise, just grow up.

I am a big fan of everyone feeling free to express their sexuality, but it is kind of a cop-out when someone says they need to end their marriage for what may end up being very frivolous reasons.
And no one ever seems to be TALKING to their significant other about these issues!...even if that talking is simply, "Hey, lets spice this up some". They'd rather just end it first or cheat.
Sorry. Rant over.

The answer my friend is blowing in the wind!

Stop staying in a relationship you don't even want to stay in.
