SIBLING ATTRACTION: I am deeply in love with my half-sister even though I am engaged

She had married and had a girl. She is now 22.

I was nervous but the family were warm and friendly. My half-sister was kind and very attractive. There seems to be such a bond between us.

I can’t stop thinking about her in a sexual way. Neither of us has mentioned that night but I think more about her than I do my fiancée.

LIRA SAYS: A strong attraction to a sibling you haven’t grown up with is a well-known phenomenon.

But I am afraid that a sexual relationship with your newly found half-sister is against the law. It counts as incest.
