As far as I know they did not. I have never read anything that would suggest that the people of St. Paul’s time had any understanding of innate sexual orientation. St. Paul uses two terms in both Romans and 1 Corinthians in referring to same sex activity; Arsenokoitai and malakoi. They both seem to refer to male prostitutes (probably temple prostitutes) and/or promiscuous men. However, arsenokoitai’s meaning is difficult to p(name removed by moderator)oint as it appears nowhere else in the Greek literature of the day. St. Paul is also talking about men in this context but the noun is feminine, so some scholars can’t make heads or tails of what St. Paul is trying to say. But in the context of Romans 1, St. Paul is talking about those who have known God but did not render him due praise and thanks and so their hearts became darkened (v. 21). They then turned to idols in the form of men and beasts (v. 23). So because of this God gave them over to various sins (vs. 24-32) Paul seems to be talking about heterosexual men and women who, because of their idolatry, were allowed to fall into a number of sins. Now many sincere, Christian gay men and women do not see themselves in this picture. They adore the one True God and believe on Jesus Christ whom He sent for the salvation of the world. They do not adore idols and God is not giving them over to promiscuity, malice, envy, and murder. For me personally, my journey in seeking God in His Church began when I was ten. My same sex attractions kicked in around 12, so I do not think that the situation in which St. Paul is speaking applies to me or others with similar experiences. I hope some of that made sense
