My brother obviously loves and accepts me as his sister, but he has acted like a guardian rather than a best friend. That was fine by me, he seemed comfortable like that. But up until recently, he has been more and more affectionate towards me. At first I didn’t think much of it, until he started acting more affectionate, too affectionate. I always shrugged it off because I really want to belive he’s a good person. But today he lifted me up, trying to ‘play’. I was having fun until I noticed his erection. I felt… uncomfortable. I felt weird. I don’t know what to say or how to feel… I’ve been a victim of s***** harassment before, and perhaps that experience has made me paranoid toward what is happening right now..? He hasn’t done anything to me so far, so maybe I’m exaggerating? Please help.
