>>918267121Feeling lust, especially as a teen, towards an objectively/conventionally attractive person is normal, even if said person is related by blood. In fact, the inherent taboo factor will make such thoughts and feelings more intense. You should never act on it, though, as it is almost assuredly an one-way attraction; if you do, you will likely irreparably ruin your relationship with that person (at best) and potentially mark yourself as a problematic member of society for life (at worst).
Having attraction towards cousins is totally plausible and not that weird (especially if you don't grow up together), but most of the time it will nonetheless be off limits for a relationship; however, a tantalising and exciting casual fling is doable if the desire is mutual.
Relations with parents and children are definitely terrible tho, while things like aunts/uncles and of course siblings could in some hypothetical case be doable, but again, extremely unlikely.
Mind you, in almost all cases procreation is something that one should explicitly avoid, except I suppose for distant cousins.
Personally I've never felt any lust towards a family member, aside from a very distant cousin that I rarely saw growing up. I have however fantasized about having a sexy sister and spending torrid lusty summers with her (I'm an only child).
