What should i think OF MY UNCLE?? ADVICE PLEASE!!?

Overreaction. Contrary to all the puritanical prudes, it is very normal for older guys to be attracted to younger females, and most wise ones know that it's a look-but-don't-touch scenario. What he did was no more perverted than the girls that posted the videos for the whole world to see. Continue the same relationship that you always had with your uncle.
