Not infidelity related, so even though it’s hard, put infidelity aside.
Who is responsible for a female orgasm?
I think it's pretty much impossible to put infidelity aside, because it totally changes the dynamics of a relationship, especially when it comes to sex.
What else can I do but stop taking blame on myself if she doesn’t get there? Does this make sense? Am I wrong?
I should also mention that she doesn’t communicate her likes and dislikes, even though I do. I also put that responsibility on her now. This is life and you need to take what you need. It that so wrong? I’d enjoy it more if I felt she did as well. She says she does even though her orgasms are few and far between. Maybe that’s true but I no longer want to feel bad about it.
I think, ultimately, male or female, everyone is responsible for their own orgasm, because even the best partner isn't a mind reader, and you know how your body works better than anyone else ever will. However, it should be a collaborative effort. I think some of the best sex I've ever had is when both me and my partner are focusing on giving each other pleasure, without an "orgasm goal" in mind.
I know how to give my WH a BJ that will get him off quickly, but sometimes it's more fun to keep getting him close, then stopping and doing something else, then getting him close, then stopping and doing something else... And my WH loves going down on me, but even though he's very good at it, and I can orgasm that way easily, sometimes it's like, "hey buddy, I have other body parts, too!" (Instead of saying that though, I usually just ask him to lick/suck/stroke another part of my body.)
I don't always orgasm, but that doesn't mean I'm not enjoying sex, and I'm okay with that. Sometimes I'm really tired or preoccupied so we have lazy sex and I don't feel like putting in the effort to orgasm, and even if my WH offers, I'm fine with it.
Post-A, I would say I've become much more selfish in bed. We still have good sex, but I don't feel like giving my WH long, teasing BJs, just because I like making him feeling good. That gives me too much time to think about him and his AP and I'm finally getting to a point where I don't regularly need to stop having sex to cry.
These days, I basically need to be on top and focus solely on my orgasm, because his AP was a really large woman and (according to him) was never on top, so that's pretty much the only position these days that's safe from mind movies.
But anyways, trying to remove infidelity from the equation, I still think it's a collaborative effort. If your wife wants to orgasm, she should communicate, verbally, with you what she would like for you to do to help get her there -- go down on me, let me get on top, lick this, suck that -- or if you're on top or behind her, use her fingers to rub her clit (or however she would get off) to achieve an orgasm.
I don't think any person should expect their partner to be a mind reader though, and just assume that they should know that they need oral or a certain position or help from a vibrator, or whatever. We're all adults here! There should be zero shame in asking for verbalizing your wants and needs in bed with your spouse.
