Dating TALL GUYS!!!!

Ladies I’m 5’2 I just started dating someone and he’s 6’4.. my question is.. how do we have sex?? I kind of get intimated because the “tallest” guy I’ve been with was 5’11.. I finally met him in person and felt shy and awkward because he’s tall!!! I of course love it!!! But how do you guys have sex with such a height difference and kiss & whatnot
