hey blazinryanc,
I can totally relate to your issue. I had started a thread a while back about thinking I was addicted to sex and my frustration with my wife sometimes not wanting more sex even though I would get it 4-5 (sometimes more) times a week, including several times a day at times where I would want to just keep going even when my wife was sore.
I would get frustrated and find myself acting cold towards her and then I would consider withholding sex (which NEVER works, btw) just so she could feel how I felt, etc, etc.
I too, would say that I'm very considerate, very passionate, the sex is mutually great, and I love her dearly...so why was I acting like such an asshole? Well...things are much better now and overall we are having more sex, but I'm also finding myself not getting into such a "funk" when I do want it and she doesn't.
What happened? I think the first thing is finding out WHY you feel that way. It's different for everyone, but for me, after 9 years of marriage, it was the fear that, like so many other couples who have been together a long time, the sex starts to wane. I was in a 4 year relationship where at first, we were having sex 3 times a day, and by the end, it got so bad I had to beg for sex and it made me feel weak that I wanted it to so much that I would resort to belittling myself just to get it...kinda like a drug addict. So even though the sex was still great with my current marriage, there was a slight drop off at the time due to both of us being very busy and of course, three kids never helps. So, my fear kicked in. I thought she didn't want me anymore, I thought we were going to not have much sex anymore and I got scared and frustrated. Instead of trying to talk it out, I thought I could "force" the issue by trying to withhold sex so that would make her want it more. I can't imagine a more STUPID thing to do and it makes me feel like an idiot that I even considered that. I mean, think about how ridiculous that is. Your partner doesn't want sex so you withhold sex? That's like your kid not wanting to go to school so you punish him/her by saying "FINE...then you're NOT going to school!".
Anyways...the first part of the solution was first realizing why I felt like I did and understanding my fears. Once I knew why, it was easier to find out who to fix it. And for me, a part of that was understanding that is perfectly NORMAL for couples to not have as much sex as they get older, busier and have kids. There is less overall time, less alone time and less time of actually being in the mood. This is much more true for women than men because their sexual moods are more emotionally and mentally driven whereas a guy just has to look at a naked boob and he's ready to go.
But the biggest part of the solution was communication. I told my wife exactly how I felt and I was surprised that she, too, felt like we weren't having as much sex and that she wasn't as "horny" as she used to be. She knew that I was being cold to her at times because of this and this was putting pressure on her and that had an adverse affect. Us talking about it actually lifted something that was slowly closing between us, and most of all it put out there for both of us to see. The end result was that the pressure was lifted from both of us and we actually started having more frequent and better sex like we had in the past. Just this week, we had sex once yesterday during the day (the kids were playing in their room and she was folding clothes on the bed and I just pounced on her) and twice the day before (after the kids were put to bed and we were smoking out and drinking wine).
Just put it out there...let her know exactly how you feel. Don't play any games, don't be coy about it...and be 100% honest with yourself and your partner.
