You should have a problem with him grabbing crotches of women uninvited at any time, even if it's not the very first thing he does.   Trump himself is the one who stated that he does indeed grab women in that manner ("they just let you when you're famous"), and he also just walks up and kisses women he doesn't know, because he just "can't help [him]self."   He is a serial sexual predator, among other serial predation activities he engages in, like ripping people off for money.
