In my limited experience…
Training qin na (nearest I get to grappling with my group) I have no problem at all with close contact providing that my partner is clean. To clarify further I don’t care if he is covered in mud, I just want it to be recent mud and not old, smelly stains. I do not care if he is sweaty as being sweaty is pretty inevitable, providing that he showered in the morning and therefore does not stink.
Bad experiences;
Training for a couple of classes in ju jitsu where I kept getting partnered with a guy who stunk. I had to put effort into not throwing up, he stunk so badly. Put me off ju jitsu (well that group) for ever.
In my group people are for the most part very clean however during an intensive attended by people from other training groups I got partnered with a very dislikeable man who had made himself unpopular with everyone due to his arrogance, boasting and constant complaining. He is fat and unattractive which would not usually bother me at all, however given his personality I felt repelled by him.
He also had a problem with excessive sweating and for some reason insisted on sparring with a bare chest, so that I had no alternative but to come into close contact with his flabby, hairy, sweat drenched gut.
I suggested to him that he might like to use a towel to remove some of the sweat before sparring with me and he cheerfully replied “Naah what’s the point I’ll only get sweaty again?” before lunging at me.
He also had a habit of being far to rough with newbies (he was reprimanded for this by the instructor) and so I was able to talk my way out of sparring with him after that on the basis that I was intimidated by him (I was a complete newbie at the time).
I know it’s shallow to not want to spar with someone just because they are physically emotionally repulsive but I suppose I am that shallow person.
Had he been friendly, likeable and not insisted on sparring only in shorts and support stockings I probably wouldn’t have cared at all.
I’m pretty sure that all the men in my group hated sparring with him too but I think it was even worse for me.
So my contribution to this would be, to attract more women
don’t be arrogant
don’t assume that women will be OK about sparring with you being bare-chested, especially if you are very overweight and have a problem with excessive perspiration
don’t stink
er, that’s it
