i need sex to feel loved

i have had my father my whole life. i am 16 years old. my father left me when i was about 13, i never had my mother. i dont know how to love myself anymore.. i dont like my body my appearance nothing. i sleep with guys. its like i let myself go so easy and i dont know why ! i look for the love that i got from my dad in other boys. i jus want to feel appreciated loved and worth something. its like i try not to but as soon as i get attention from guys i feel so good about myself 💯 in that very moment that im giving my body to them i feel loved , i feel like i need them to be happy and stable. i have a bad name for my self now and i feel even worse.
