What should i do about this situation :/ ?

Okay, so theres this guy thats liked me for awhile but i never really liked him as more than a good friend. and he told me he liked me in october..i had to say i didnt feel the same , then we stopped talking until about christmas break he started texting me again. we talked and i admitted i think i liked him a little during the time we didnt talk. he said he liked but i told him id likedsomeone else now. in the beginning of january he started asking to do stuff with me, even if i didnt like him like that , but he would for "experience" because ive never had a boyfriend. he told me how far he's went and stuff and said he was ually attracted to me. but again i told him no and that i wanted to be just friends. mid january he texted me asking again andi said no but he just wont understand. hes like youd have fun, you can trust me, id do anything for you. and im like no i really just wanna be friends. and hes like well we could be fwb's then and just stay friends cuz iwanna become close friends with you. i told him no again..even though ive said things that maybe led him on before. but now he wonttalk to me since ive said no and doesnt get the point i just want to be friends. how do i get the point across ? or should i do stuff...for experience since i kinda need it.i dont wanna just stop talking to him even though we already have but hes the only guy ive ever really trusted as a friend. and btw , he wasnt trying to use me...because hes honestly spilled his heart out to me and i felt terrible not feeling the same.
