Ok people, first of all thank you so much.
2nd, I do masturbate since I was 12, it's no biggie, but being "sexually compatible "? trust me I'd love to have sex with her but we just want it to be special, she's the only female that could turn me on!
I don't think you understand what 'sexually compatible' means.
At the very leas, I hope the both of you have several long, very in-depth conversations on sex, your wants, needs, and desires.
Sexually compatible isn't just about sticking Rod A into Slot B and going at it. It's also about meeting each others needs, wants and desires. If you end up wanting/needing sex 2x a week and she thinks once a month is good enough for her, so it should be for you as well, that's a big problem. You'll be getting sex once for every eight times you actually crave it. You don't think over years of this it won't cause some level of building resentment? If not, read some of the posters on this board. Heck, PM me and I'll tell you my story. I'm divorced and while I'll never say it was solely due to sex, I will say that if our sex life had been remotely compatible, it would have helped to keep the relationship more positive during our moments of stress and maybe wouldn't have caused so many other issues as well.
What happens if you want to try different things down the road, such as oral, role play, lingerie and doggy-style, stuff that is really pretty basic compared to some of the other stuff out there, yet she tells you it missionary position or nothing? Are you going to be happy with that? What if after you have a child she tells you that she's no longer 'in the mood' and that if you are that's 'your problem'?
These things happen A LOT. These types of stories are found all over these boards. And plenty of other issues as well. The 'we were sooooo in love before we got married, I just figured it'd stay that way' line has been posted 10,000 times on these boards I'd wager, and each by a man/woman who swore they were fine and didn't have to worry about being 'sexually compatible.'
Sex isn't like most other things in a marriage. If you need some more money, you can borrow some or get a part-time job. If you are down and needing a boost, you can go out with friends or your family. There's alternatives to your wife. But when it comes to sex, if you can't get your needs met with her, you are SOL. It's either stay in that situation and be unhappy, have an affair (and get rightfully lambasted by society/family/friends) or get a divorce.
Being sexually compatible is a very important part of being married. I know. If you don't think it's important in your case, I hope you are right and I wish you well. I wouldn't wish a life of sexual frustration on anyone.
