Its about new sexual experiences and getting to know someone new and interesting. The mutual trust and non-judgemental attitudes are refreshing. When the lady I'm with enjoys her time with me and the way I make her feel, I leave feeling good. I'm also probably a sex addict, so I can spend lots of time and money in therapy to overcome it, OR I can spend time and money indulging it. The latter is more fun!
I love all kinds of new experiences, not just in the hobby. The hobby allows me to meet ladies who are open to new things as well. Age, race, size, looks, personality, background all seem to get set aside to enjoy each others company. There's the fantasy side is indulged.
I've had the pleasure of have a couple of previous girlfriends that were open to experimentation, learning and teaching. I learned a lot very well. I use those sexual skills whenever I'm with a lady, always taking her preferences into account.
The hobby allows me to see beautiful ladies, enjoy their touch, enjoy touching them, watch their reaction to the touches. Take them to a little fantasy as well. I have many more reasons, but that would be a book. I also meet some women not in the hobby. It's all good.
