i was hanging out with this guy who i like and he likes me. we were drinking and (oops) had sex

i felt rly dum the next day and felt like i made a huge mistake! i spoke to him abt it and we were cool (he didnt think i made an ass of myself). then we hung out like 4 days later and we hooked up again. we didnt go as far this time but i felt stupid telling him i dint wanna take my clothes off since thats a step down. i want to start from scratch! i really like him and i dont want him to think of me as a booty call or fuck buddy or anything!
do u think i killed my chances already?
what should i do? im having trouble figuring out if he stopped liking me as a potential gf now!
