You don't need one. This whole bullshit over sex is overrated. It's a fucking instinct, and look at us, humans. We've gone so far exactly because we denied instincts.

Thing is, nowdays sex lost its purpose. It's just for fun. And living for "having fun" is ridiculous, since it's all just a fucking chemical reaction in your brain. You'd be the happiest guy in the universe if I injected the same chemicals responsible for pleasure, directly in your blood stream.

So yeah, have sex or giflriend whenever you really think it'll bring anything worthy to your life. There are more to do in life than stick your dick in a meathole anyway, but too bad most people disagree, just because "zomg it's so good so must be my purpose in life"
