This is a fairly common occurrence especially among youths. The important thing to keep in mind is that like with most feelings, they will eventually subside. Think of the complications any decision could make in the long run and act accordingly.
It's totally common, jesus, young lads with hormones rushing everywhere, or girls for that matter - jesus, they could find a bloody plant pot attractive!! The fact it's your cousin makes it just a LITTLE bit too hard to express.
Just don't act on your urges! Thinking is fine, it's acting on those thoughts that's a no-no!
My great uncle (my grandad's twin brother) married his cousin. My grandad was going to marry her sister but luckily found another girl and got out of that!
