i need some advice

i lost my virginity the other day but i'm only 14 and going into sophomore year. some of my friends think that you should wait to have sex, some of them are against it and others feel it's my decision. i'm scared to tell certain friends because i don't know how they'll react. i've told two of my friends because one of them has also had sex already and the other one is my closest friend, so i couldn't keep the secret from her. i don't know what to do because i'm not even dating the guy i slept with. we have a friends with benefits thing going on and it's been going on for a while, we just never went all the way. i need opinions on if i should tell my friends or not.
