So this comment made me remember a really funny story from about 2-3 months into HRT on my part.
I was out drinking for the first time with friends since coming out to my friends, i was at the point of dressing more on the effeminate side, but was not full time yet. One of my friends is talking to me and goes "dude, look, your growing tits!...You going to start dressing the way you intend to soon?". This led to more questions (he is super accepting and supportive of me, as are most of my close friends.), and eventually we are both pretty tipsy and walking back to my place where he and two other friends are going to crash so i can get a ride back to my car in the morning. While we are walking, he asked "So are they sensitive...like, do they hurt?" and i responded by telling him "Only if something brushes up on them or hits them..." at this point, my drunken mind goes "for example" and i say "like this" and hit myself in the chest...followed by me screaming out in pain and collapsing to my knees...
So yeah, i quickly learned that 1. my friends still laugh when someone is in pain, 2. they are all cool with my transition, and 3. dont get drunk and hit your own breast to show that they are sensitive...it is painful as all hell.
