"*However I also know the last time I was actively 'out and about' was in college. So much has changed since then for me and for the people I may date. I won't know for sure how I respond physically to someone until I have that attraction and desire for someone again. It will happen, some day. No sense over-thinking it. "
Great way to put it BobbiJo. Until you are in the situation, you can't say for sure how you'd react. If the attraction is there you may respond, even if you thought you wouldn't. I don't believe that sex is ever meaningless. There is always some reason for it....whether everyone else approves of the reason or not. I think the important thing is being true to yourself and maintaining your self-respect...which I believe can be done while having sex with someone you have no plans to marry!
