Virgin into incest

Im a male 21 years old Im a virgin but im very sexual. for most of my life since I discovered masturbation I've thought of everything to jack off to but my favorite is my family ever since I was young I've wanted to have sex with my family my mom, my dad, and my sister she's older than me. i don't know why I want it but it imediately turns me on any time Im around one of them which is almost always I think about having sex with them right then and there and Im honestly not sure what to do about this. do I act on it or let it be?

I'm a lot older than you and have yet to hear of anything good
coming out of incest.

Sounds like you're just diverting yourself from getting into relationships
outside the family.

I've never been good in relationships They end up wanting sex and I don't want it with them idk if it's fear or that I know it won't satify what I really want

Your family are almost certainly not going to be feeling the same way as you. So acting on it is highly likely to cause problems for you. Emotionally. And possibly legally, if they are upset enough to go to the police.

I'd keep it as a fantasy. And try to expand your sexual horizons a little. It's OK to have fetishes! But can be hard as an adult. If that fetish is the only way to satisfy you.

It might also be worth exploring some of this with a counsellor. If it's fear or some other core issue. Blocking you from wanting sex with unrelated people. They can help you work through that. That seems a healthier approach long term. More likely to find happiness that way.

maybe I should do that I just get so lost in the thoughts of us all together I think it'd be amazing but it would more than likely be hard to handle I'll definetly keep it as a fantasy thanks for the help
