Actually, I took the dance class years ago with my then girlfriend, now wife. It was actually at her suggestion. She had taken dance classes in college and wanted to take classes again after she had been away from them for a few years. However, she didn't want to take the classes by herself. She asked me because I had previously gotten her to jog with me (something she really didn't like doing) by telling her that I wanted to start jogging again but did not like to jog alone. Against that background, I really could not say no to her request that I take the dance classes with her. I guess dance class was her way of getting back at me.
As to whether my wife tolerates my fetish for tights, all I can say is that some of our best sex ever has been when we were both in tights. The first time occurred after we went back to her apartment after one of our dance classes. I got really turned on by seeing her in her white, shimmery tights, and I practically attacked her while I was still wearing my black tights. The feeling of our legs coming together was out of this world. Needless to say, we had many more such sessions. We even experimented by having sex while we were both wearing sheer pantyhose. That sex was even better than the sex we had while wearing tights.
Everything I have just told you is absolutely true. Feel free to share my experience with your girlfriend. No one can be more heterosexual, male or into sports than I am. I truly don't know what it is. But, there is just something about the feeling of tights/pantyhose that I find indescribable. Good luck with your girlfriend. I have a feeling you are going to have some fantastic times ahead of you. [/i]
