Is grind dancing bad?

I've done it before many times, but I always make sure I never get too crazy with a female because that's how the way I am. I've seen dozen of people do it all the time, and I am a Christian so I try to follow the Lord by doing the right things. I don't see why it may be a problem, unless it leads to sexual intercourse then I won't do it. I'm just dancing to have fun and maybe a little crazy, but that's about it. I don't drink beer and I never will, and I'm no alcoholic and I never ever will be. I may have had a whole glass and a another half of beer when I was 15 at the time I was in Germany, although it wasn't my idea because I just wanted to have milk. Other than that, I've been a soft drinker as long as I known. If I ever decide to go to a dance club with someone I know that I can trust and be next to, I'm not sure I'd still question it because I've read other answers, according they say going to a dance club as a Christian can be a sin. I'm turning 22 tomorrow, and I'll probably just eat dinner at Outback, but I don't know about grind dancing.
