What would you call this?

With all the talk of sexual assault going on right now, I have a couple incidents that I'm curious what to call. To set up, I go contra dancing. It's similar to swing dancing, so this is not a club type situation.

Incident 1: a man feels my breasts while twirling me.

Incident 2: a man pulls me up close and rubs his erection against my leg while dancing. I was 22, he was in his 60s at least.

What would you call this? I know both make me incredibly uncomfortable, even though they happened years ago.

Edit: obviously what happened was wrong. Being more mature and more sure of myself now I absolutely would call attention to it if it happened today. I don't know either man so I can't report it unfortunately. I guess I'm mostly wondering if it's assault or harrassment. The line between the two is blurred and it's hard to say where it crosses into assault.
