This is true. The problem is that people infected with Same-sex Attraction Disorder (SAD) have an even harder time remaining celibate than healthy people do. SAD demands attention and many partners. That's yet another reason why SADs should never be priests (or be allowed around children), they can't keep the vows.
Remember:
To the heterosexual sex is what they do
To the SAD sex is what they are
God Save America (Please)
This is true in general, but particularly so in an all-male priesthood. Imagine normal men, surround by willing and able females. That's what it's like for homosexual priests - and a strong reason why we shouldn't have homosexual priests.
