Gent here. No, you are not in the minority. You are in the majority and I am in the minority.

To me, what a couple do in their privacy is their prerogative. Personally, it isn't something I could do or would feel necessary to do. My ex, and the one female I am still in love with, felt the same as I did. We never did that kind of thing and didn't feel the need to. In fact, we shared intimacy together and didn't need to do anything else away from each other. That was just us. I would just rather make my own love, not watch someone else's. The only person I ever wanted to fantasize about was her, no one else. Luckily for me she felt the same, and I can't find anyone else like me.

I have talked to a lot of people about this, and they all seem to think this activity is normal. It just isn't for me, but their certainly isn't anything wrong with you and if you both have an understanding and enjoy it then there is no problem. Carry on.
