It can be for pleasure, in MARRIAGE. Gays (According to God's definition of the term according to my beliefs) cannot marry.
However, God created sex to be between man and woman in marriage, so any other way is sin. It has nothing to do with procreaton.
Why does love require a ceremony?

Marriage is just two individuals saying they will love eachother forever. Gays do this too! It just isn't legal because of social authoritarianism.
Therefore, since a marriage is just a union of love, clearly, God doesn't mind sex at all provided it is with one you love and are devoted to. That love and devotion does not have a difference between sexual orientation.
Some guy with a Bible declaring love valid does not make it any more so, especially if you consider half of the people get divorced anyway... God's a libertarian, he won't approve of any church hierarchy.
Also, Jesus DOES speak on it I just found out:
Matt 5:18 "For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled."
Which, is talking about the moral law which still applies, not either the Ceremonial law or the legal methods of punishment in the Mosaic law.
Perhaps my Biblespeak isn't quite fluent, but I'm sensing that line is VERY open to interpretation... it's akin to several clauses in the Constitution. It can mean little or a lot depending on the beholder.
Specific statements are needed - where does he speak of homosexuality being wrong? I recall lots and lots of love being mentioned, but no "homosexuality is evil."
In short, I don't think a homosexual relationship is any of Big Brother's business, but its still wrong because... God says it is.
But why would he say it's wrong?
I'm not hurt at all.

In fact, I'm happy I've come to terms with who I am. The only thing that hurts me (physically and emotionally) is the people who won't accept the lifestyle, either out of tradition or an unwillingness to analyse things beyond what a Bible verse says.
Never mind, lots of things hurt yourself but aren't sins. Why is tanning not a sin? You can get sunburn and do a lot of damage. I mean, if drugs and whatnot are sins God should at least be consistent and make all forms of harming oneself a sin...
Hence why I think "harming oneself" is illogical as a sin. Sin should be defined as acts that harm others and their happiness. Rape, murder, assault, thievery, deceit, intolerance. Homosexuality, drug use, and anything consensual therefore cannot be a sin.
