I would exclude any orientation that is directed toward exploitation, coercion, or cruelty. If you're inflexibly ephebophilic, you have a good chance of engaging in reckless and exploitive relationships. If you were charged criminally, as many are, you probably wouldn't regard your orientation as a gift. Contrast that to you being the fourth brother in a family of heterosexual males who marry and have lots of kids. Let's say you also have a partner and decide to foster. Your minority orientation in this setting, it seems to me, not only shines light on your gift but on the obvious gift of your nieces and nephews. The situation becomes an occasion of grace unless the gift is rejected as "not as the manufacturer intended."
