It's great if someone wants to wait. That's their choice and I respect that. I just don't like the people who push that same will onto others or look down on them if they have had sex earlier.
Personally, I feel like if you are with a person that you care about, then it's fine. It's love and it's life. Things happen. But it's someone whoring around just because they want some action, then I might think more negatively on them, and their choices. But it's not like I would try to control them. Actually, I'd probably just keep my thoughts to myself.
