Is it normal that my friend has this fetish?
I am a girl and I have a twin brother. After a few drinks, a guy of ours revealed to me that he often thinks of my brother and I together in bed. My brother and I are very close. My friend said that becoming closer would be hot and he would want to watch. I think it may have something to do with us looking alike. This is really bothering me. I just can't get it off my mind. Do people normally have a twin fetish?
