Some do and some don't. Homosexual behavior is not just found in humans, but has been observed in dozens of other species, and not just primates. Pedophile behavior has also been observed in animals.
I don't believe there is a "homosexual gene" either, but there is no behavior known to be attributable to one single gene. It is multifactorial. IMHO, the chance of discovering any gene set that results in any particular behavior is just about nil.
One thing that always interested me about gay men. Ask them at what age they realized they were "different," and invariably they answer 7 or 8, about the same age heterosexual boys start to realize that girls are "different" from boys, and start to treat them differently, not just as "another playmate." The true pedophiles say the same. So, at the time of "sexual awakening," most look to the opposite sex, some to the same sex, and some to young children.
