Yaoi/gay love addiction...is this an adolescence thing? is this normal or not? SOS!!!?

I've been going through the same thing reading slash fan-fiction lately. It is most likely just hormones running wild... If you can't focus in school, though, I recommend trying to avoid it for a while. If you started at 10, the general age when puberty starts, it's most likely just your hormones... Don't be too freaked out about it.
