it's just.. it's gets me time to be comfortable in so close situation. to realize it's happening makes me a bit shy, but more like thinking that "i'm getting hot too.. what if i would do something embarrassing?"
like once when i was kissing with my ex bf and i was on the top, my boobs where almost out of my bra and it took much time for me to realize it. he liked it, i'm sure, but i was like "no no no.. i'll wear polo next time!"
