I'm a 19 year old man, last month me and my little sister were messing around play fighting. My sister is insanely competitive and was taking it really seriously so I decided to let her win. So she gets me in this move where her legs are wrapped around my waist and she's squeezing. She does gymnastics and has strong legs so this actually hurts me and I give up.

Only she doesn't let go. She starts saying how I have to call myself a '*****' and she'd let go. I say no, then try to escape for real but I'm too weak. About 5 minutes go by of this and it really hurts so I just swallow my pride and say it. But then she tells me to repeat some other humiliating stuff including calling my girlfriend a *****. I say this before realising she's not letting go, I try punching her at this point. She grabs my arms and restrains them. Eventually, I puke and she still doesn't let go until like 30 seconds after that. I cleaned the puke and didn't tell anyone as she told me to. My ribs were really bruised, I told my mum that I slipped in the shower.

I feel so emasculated, I can't speak to anyone about it because they'd laugh at me. I already think I had a depression disorder but this has just increased that tenfold. This is like the most pathetic thing I've ever typed out. This isn't even the only incident either. What should I do?
