I relate to some of what you wrote, MR. I very, very rarely turn down requests for sex from my boyfriend - even if I don't start out feeling horny, it always excites me to see him aroused, and I'll invariably work up to it in a few minutes. I love having him inside my pussy, mouth, and ass and being able to bring him pleasure. One thing I need to work on is initiating more myself - I'm a textbook submissive in a lot of ways, and really prefer to have my partner make the first move. I ended up with a fellow submissive, though, so I'm trying to reprogram myself and find ways of asking for sex when I'm horny, even if he's not hard and I'm feeling discouraged. He's assured me that if I initiate, he'll usually be up for following through, so I need to try to do that more often.
One prevailing theme on this thread seems to be that everyone wants their partner to take time to re-connect with them, take their needs into account (emotional, physical, and practical), and make an effort to be the person they fell in love with. Not all of us give up on life once things turn serious - I still make every effort to make delicious desserts, exercise, and try new things in bed in the hopes of keeping things fresh. Granted, I'm not married, but I'd like to hope that if I were, that wouldn't change.
