I have a pretty high sex drive, to the point where it can get distracting, but I'm good at putting mental barriers in place. So I can say to myself "nope, not this one" and actively put people into the friend zone. I have some very clearly demarcated lines in my social circles, in my own head, and I just don't cross those lines. Once I flip that switch, it's actually hard to flip it back. Sometimes thoughts still creep in, but if someone is in the "off limits" category in my brain, that's usually enough. But you have to really mean off limits. Like it will not happen. Ever. I think some guys still fantasize about "well, maybe..." Whereas I truly file it away as impossible.

Of course it also helps to get laid regularly. That way, you're still satisfying your urges, not suppressing them. So if you start to get horny, you can channel it into anticipation for the next time you see your partner, and take the focus off the present moment.

I'm with you on that; the majority of my friends in my teenage years were female because of it.

I don't have any sort of sex drive though, so can't relate to the rest.
