I know you're not supposed to look for reassurance but, I need someone else's perspective on this, and I don't feel comfortable telling my family about it.
So I was hugging my grandma, and I was afraid of my nipples touching her while we were hugging. And then I think I was like, stop letting your OCD not have a good hug with your grandma, so I think I moved my chest towards her, because I was holding my chest far back from her when I was hugging because I was scared of my nipples touching her (I know this is really gross sorry)... if I was, it wasn't sexual, it was because I didn't want my OCD to affect my hug with my grandma if that makes sense. Then I started googling stuff about breastfeeding and arousal? I'm not sure how that really had much correlation to the "situation" I was dealing with, and I feel guilty for searching that up as a way to maybe validate what I was afraid that I did. Maybe because I was thinking that some mother's get arousal when they breastfeed, but they breastfeed anyways, not because they want to feel arousal, just because they need to feed their baby. I could have been relating that to my situation because I know I wouldn't have tried to do that for arousal, and maybe I tried to as a compulsion (again, I don't really think I did try to have my nipples touch her, but I was scared that I did). I love my grandma so much, and I would never want to ruin my relationship with her. My grandma only has me, my sister and my mom, so she relies heavily on us all.
