Is it wrong to have a sexual attraction towards your brother. I just noticed it last year. I always stare at his body when he takes his shirt off. He has a hot body. Also, when his shorts roll up his thighs I get aroused. He has a great butt and I like to smack it and I also grabbed his penis. He asked me if I was gay, and found out by seeing pictures of shirtless guys on my phone. He is the only person who knows I am gay, but he doesn't know of my feelings toward him sexually. Other things I do are look at him naked when he is about to shower and put my face in his underware. Should I tell him? Should I act on these feelings?
