Actually, too many people assume that same-sex individuals are only attracted to each other because of sex.  
Nobody asks heterosexual individuals if they are going to live together in deep friendship and love as two friends without any sort of sexual contact. In fact, today, many heterosexual couples live together for quite a time before they marry.  Is there sexual contact?  YES.  And artificial birth control is utilized as well.  But family members, relatives, and most parish churches don't ask any questions about this--if and when, the couple applies to get married.
But same sex individuals---are put through the wringer because they don't live like eunuchs.  In the history of the church, we had popes, cardinals, arch/bishops and priests [all who took a vow of celibacy], who abused girls, boys and women---and their actions were despicable.
