Thanks for the support...I'm home now and laundry is being done.
I posted about it on my private FB page and was also given the suggestion to contact security which I did the next day...but I think I went to one of the Convention center people (blue and yellow shirts) and he had a great big 'so what' about it. I think I will follow another poster's advice and contact GenCon.
The first incident was in the new part of the vendor hall and could have been a pickpocket. Guy got really close and rubbed and I said "Hey" so he scooted off. Of course, a pickpocket who thinks that a woman keeps much of anything in her back pocket isn't a genius but then...if he was smart he wouldn't be a criminal.
Second one was a definite pinch and the guy laughed as he walked off. It was a garden-variety ass grab.
Frankly, I was super shocked it happened at GenCon. People in the gaming community may blow me off occasionaly for my gender but none have invaded my space like that before.
