I have friends who have been gay from the day they were born and have never changed their sexuality because it is not possible for them. I am just saying that the majority of folks practice a sexuality of convenience. Most of it is really a result of broken families where people are just looking for love anywhere they think they can find it…
The friends I have with permanent STD’s didn’t get them by being deliberately promiscuous. Most got them from compromising themselves at a point of loneliness or weakness and now have to live with that for the rest of their lives. And even when the result wasn’t an STD but an unplanned pregnancy, it is still hard to look a child in the eye knowing that either your lust or your loneliness created a life that should have been made out of love.
