I applaud and respect your stand. That is great for you.
For me, though, I think if I were going to marry someone, I would want to know whether I would be compatible with him sexually. I know sex doesn't constitute the whole relationship, but it is an important component and one that should be considered, IMHO. It's a deeply personal thing, though, as well.
For me, I would have to be committed to the person to have sex, but not necessarily married. I think if two people really love each other and want to spend their lives together, they should be able to have sex even if they are not married.
