I'm confused as I'm amazed

Sounds like it's becoming boring to you. Sit and really do an introspective search as to what sex really means to you. We all go through phases, but I'll bet you're just learning that sex is not just about sex. Learn about intimacy and see if that does it for ya...or maybe you just need a new fetish.;)

@... You are fine. As you mature your conscious frontal mind more easily overrides your instinctual mind. You also say you just had a wild week so you are spent. Men's sex drive is peaked at puberty and decays with a few smaller bumps back up here and there until death. The evil catch22 nature throws at us is women do not do the same thing. They start low at puberty and rise more quickly through their mid 20s before peaking in their mid 30s then the downward spiral. You are learning the true difference between sex and intimacy from the sounds of it, it is a good thing.
