I gave a jab at yours since you gave a jab at mine. Not to me specifically, but more generally.
You: This sex act is only done by teenagers. It's lame.
Me: No. Not lame.
You: You just said my sex life is bad.
Also, "foreplay" is a word I don't much like. Blow jobs are sex. Unless you think lesbians never have sex, since it's mostly going down on each other and using hands. I really hope you wouldn't suggest women can't have sex with each other.
My jab at you wasn't subtle at all. I was insulting you very clearly. In my mind, the insult was because you made a broadly insulting statement about the sex lives of others. You seem to have the attitude, "The fight started when you hit me back!" I hit back.
All that said, it wasn't right for me to suggest you have a bad sex life. It might be the best sex life ever. (I'm not being sarcastic or disingenuous when I say I realize you might have a fantastic sex life.) I just have a difficult time holding back when someone makes statements about sex acts that I find inaccurate and perhaps a bit mean. It doesn't mean my behacior was mature -- it wasn't. So I apologize for being a braggy brat. (Though, one more note: I think it's good for people to openly discuss sexuality.) But yeah, I was being a jerk. I'm sorry.
