DP/DR stole the two/three years of my life during which I should have experienced all of that (those were the few years it was at its worst). Even though I'm quite a bit better now, that is something that the disorder has ruined for me: that time of life when you're supposed to play around like that. I'll never get that back. Now I'm playing catch-up but I'll never feel quite content with that side of life. Now it all seems so scary when it should've been fun. Part of me doesn't even want it (sex/relationships) because the whole process has been fucked up cos of DP/DR.
Sorry, rant over. I know what you're saying though pal. It's difficult. I'm guessing by your username that you're 17-ish so you're more or less in exactly the same position as I was. It's difficult to give advice because I don't know how badly you're feeling but if there is just that little spark of intimacy in you, take advantage of it. Don't waste it. I had nothing (to the point where I thought/think I'm asexual). But judging from your question, you do have that emotion in you, which is great because a lot of people with the disorder lose it completely. You've got that need to find someone and that's great. First times are never an easy thing either way but who knows, DP/DR might even help in this case in terms of distancing yourself from the moment (if you know what I mean). I'm rambling like fuck cos it's late and I'm pissed off with life but all I can say pal is go for it. You've got that desire in you so embrace it and it could help you big time in getting out of this mess of a disorder. All the best!
