One, a girl who I was really in love with, or thought i was was (I was 19) asked me to hit her/slap her, hard in the face, asked her to do it first, but I did..kinda liked it, we drank a lot, I'm sure both of us were really drunk when that happened. Never did the choke thing, but I may not even remember if I had, both of us had bruises sometimes the next day.
