I still feel a twinge of envy many years later -- I'm twice as old as some of these kids and at this point have had plenty of experience.

An absolute no-sex-before-marriage upbringing led me to completely bind up and lock away a lot of urges I had as a teenager, to the point that I didn't really want to explore sexual feelings and experiences with someone: I knew what I wanted and just didn't want to deal with the impossibility of it all. I didn't really date or pursue anyone for this reason, to the chagrin of people who were attracted to me (and to whom I was secretly attracted, too).

I don't think that's a great way to feel, and yah I still feel envy when I hear from friends about their early experiences, especially when they are free of hangups and all about two people learning about each other and having fun.

Since I have no idea why you haven't had sex -- you sound like you want it -- I can't offer any advice other than this: Be honest with yourself, comfortable with yourself, and make friends and acquaintances. Be genuinely interested in those people, their lives, needs, and desires. Be open about yours. Have real-world relationships, participate in real-world activities. You're not going to get any by sitting at home alone stewing.
