Confused about sex

so i’ve been dating this guy for a while now and we haven’t done anything sexual together , but he sends me snaps of his boxers and body and he do be packing down there 😝🤭 also he is obsessed with my boobs and ass and he turns me on alot

i think we are both shy cause we haven’t done anything so far

I DONT KNOW WHAT TO DO OR HOW TO ASK HIM 😩
