That's a good question which deserves a thoughtful answer.
Everyone's read about my "lingerie modeling" experience a few weeks back, and I made out with a girlfriend once, but that's the extent of my experimentation. (The latter was one of those moments where the world seemed to stop, which I'd yet to experience with a guy at that point. I have since.)
I think women are the most beautiful things on earth, but they lack that male strength, and that male energy that turns me on. I don't get the deep down tingle from a beautiful girl, it's more of a philosopher's appreciation of beauty, coupled with curiousity. Maybe a little bit of exhibitionism in there too, because I can't imagine doing it without an audience of my man.
I definitely want to experiment more, but I have a feeling it would come out to be "making love to something beautiful", and not "making love to someone I love". In other words, paying homage to the pussy, not expressing my affection. Does that make sense?
