We did some research when I was in college (in the very conservative South) and found 6 total admonishments against acts that could be interpreted as homosexual. But then we found 211 admonishments against various heterosexual acts. You can guess which list the evangelicals conveniently ignore.
One of the verses condemning homosexuality in the New Testament uses a term that can be translated as referring to male children rather than adult men, which in cultural context, would make sense given the dominant regional culture at the time featuring a lot of pederasty. However, the Old Testament verse condemning it, and the other New Testament verse are more direct.
