I have read all the ideas put forward, and the words I think, that are missing, are sex and love. Masters, subs, spanking and all the rest are sexual, and we have no control over what turns us on. If there was 2 downloads available to me, one being a S&M movie, the other being a full length porn movie, full of celebs, but I could only have one. Every time I would go for the S&M, because its what I like.
So if inside you, you have sub tendancies, but the man you marry is not a dom, your sexuality will feel unfufilled, and the same for the other way around. But if you have a sub personality, and you meet and fall in love with a dom, the sex will be fantastic.
The last thing I will say is, if a sub female marries a sub male, the relationship will be terrible. I have seen it. Mick
