Thx, guys for your support!
If You are interested, everything went pretty well, and there were no "troubles" at all. I think the problem was that we didn't know each other for long time when we tried first, but now, after we've been dating for two months and talked everything through, everything went remarkably well

More to that, I feel much calmer and stable, than before that. More to that, I started playing guitar again, you can call it creatibity boost)

I guess, it is true, that abstinence is a bad thing, now I understand that, and won't repeat such mistake)
