Three words....
Because its easier!
In the short term anyway its far easier to not wait. Having been dealing with the accusations of being gay and numerous other similar things for years I can tell you waiting is probably the hardest thing to deal with as a christian especially since the media is so focused on sex. The bible says we are to avoid the appearance of evil, but how do yo manage that when the very act of avoiding the appearance of evil (waiting till marriage) makes you appear evil (gay) to the rest of the world because you aren't sleeping with every woman who comes around. Being a celibate single male isn't easy in this world.

The Bible agrees with you so much that it commands that every man should have his own wife, due to the danger of fornication -- start of 1 Corinthians 7. A healthy sexual itch demands marriage, though one (if a believer) must marry a Christian, and before that pray & trust the Lord for wisdom (James 1).
