I like to have sex with men and women at the same time

I have been fucking my ex brother for almost a year and I still haven’t been able to get my ex to stop trying to fucking me while telling him I have been messing with someone

I want someone who wants me not someone who wants a place holder until that get into their next relationship and not a egotistical narcissist who wants to use me I want the same love I give back I wish my friend gave me that but I just feel like a place holder in his like not anyone serious just someone to be in place of the female he is looking for we do everything that looks like a relationship and then he turns around and says to my face that we not together and we are friends and that’s it that’s all
