No. Sex, in and of itself, doesn't solve anything except horniness. And the horniness comes back real quick with a vengeance when you're college aged :-)

Do everything possible to get out of your room and meet women while you are in college. Be neatly dressed: doesn't mean trendy or a fashionista, just wear ordinary clean clothing. Join clubs, take up a hobby, randomly walk around with a smile on your face.

BE PLEASANT. Seriously. Practice smiling if you must, but no one wants to talk to a grump. Talk to people. A big mistake is to confine yourself to talking only to attractive people. Talk to anyone who will respond and shut up if they don't. Say hi to that strange chick at the bus stop: the one with the lazy eye, a unibrow and a humpback. She's a person, be nice to her. Greet people with a "hello" and a smile, hold doors for strangers, help the old lady with that heavy bag of catfood.

In short, become a nice person and people will want to be around you. Once that happens, the whole women/intimacy/sex thing tends to take care of itself. The species has managed to propagate itself basically forever. That wouldn't happen if it was terribly hard to hookup.

In order to meet girls, you have to talk to them. Most of them won't just walk up to you and bite you on the ass. Get out of your shell, stop worrying about being awkward. Trust me, the women are also worrying about stuff that you would think is trivial: we all have our insecurities.

Wasting money on a hooker is avoiding the responsibility for changing your own life. You'd be better off spending it on a therapist.
