nervous af please send advice my way

okay so compared to my boyfriend, i'm really not experienced. i've only ever made out with people and he's had sex before. so we had sex today (my first time) & he was doing all the right things and did things to me and i felt awkward that i wasnt doing anything to him. and i feel really hesitant to do so because once i tried to give him a hand job and later he told me ( in a polite way, i just overthink) that he wants me to be more agressive. but i literally have no idea what im doing. and i wanted to do something, anything to him today but i kinda just froze up and let him go on. and now i feel annoyed with myself lol. anyway: i need advice on...well basically how to please him since im hella inexperienced
