I think my sister is too hot and it's affecting our relationship
Affecting your relationship in what way?
I find it too hard to get intimate with her. She's such a sexy girl and I can't keep my eyes off her
It's gross to be attracted to your sister. You should only be attracted to people outside of your family.
Are you saying my sister is not attractive?
Please don't try and deflect from my statement. We're not talking about me, we're talking about your sexual attraction to your sister, which isn't okay.
