friends with benefits

What would you do in this situation?
I am 17 years old and i’ve never had sex.
Four months ago i was close with this guy and we were working towards a relationship. However, halfway there we realised that a relationship between us would never work.
But the sexual attraction is after four months, still as strong as before.
So he suggested to have casual sex without a relationship, aka friends with benefits.
In one way i would like that because we definately have that sexual attraction towards eachother, but in another way, i am not sure that its ok to have my virginity taken by someone who im not in a relationship with.
Do you think i should just do it because sex isnt that big of a deal, or ignore the sexual tension and wait for someone im in love with?
