It's really not for me. I saw a girl regularly who was very into being a sub but she wasn't with me as I'm all about a GFE and me being submissive is a BDSM sort of way (or any other way now I think about it) is never going to happen.
Even spanking does nothing at all for me, I've had a couple of girls ask if I'd like to spank them, I did once but it did nothing for me so from then on I've always politely declined.
No reason why people shouldn't discuss it here though, I'm sure there are plenty of people who are into it and would appreciate threads and reviews.
