The filter, which most 'normal' people have, is for taboo sex and such. But what if you suffer from hyper-sexuality and an OCD which results in intrusive sexual thoughts without absolutely any filter?

For example, you are with a woman and you have no problem fantasizing about incestuous sex, involving the woman's female family members (sister, mother, daughter) or the male family members (brother, father, son)? You cannot help having these intrusive thoughts that literally anyone is good to fuck and have fun with, their relation with you or your partner does not even matter. The woman's female friends too are not spared from these intrusive thoughts. Really no filter to keep anybody out of these fantasies.

Swinging and sharing your woman also makes for a huge amount of intrusive sexual thoughts. Nothing wrong with this lifestyle but it is intrusive if someone is not into it and it is just you fantasizing it.

Maybe hyper-sexuality is the result of an OCD? One of the well defined symptoms of an OCD is = Sexual Preoccupation. So, what if OCD is the cause of all hyper-sexuality? Rather, what if hyper-sexuality is an anxiety behaviour even without qualifying as an OCD?
