Interesting question. I've been thinking about it and I think technically, Ethel is correct (quelle surprise - I'm disagreeing with you yet again.)
A homosexual is attracted to members of their own sex. A homosexual who is attracted to minors of his or her own sex is a paedophile.
You can't be both things at the same time.
Another example is (say) a bisexual woman. If she dates a fella, then a woman, then another fella...she's not straight, then a lesbian, then straight again. Her core being is bisexual.
(Actually, I don't believe in bisexuality...I think it's just people being greedy and having no manners).
