Advice/opinion much needed!

So i met this guy and we hit it really well off and have a thing for like a month or so now... but as i learn things about him the more and more i get skeptical.

He is really into sex and i am still a virgin sometimes it looks like he respects it and sometimes like he really wants to do it ... not all the blame is on him tho because when im with him my sex drive goes really UP and i just wanna do it but than again i dont want him to get the wrong idea about me (since its been only a month). (He is 20 and im 19) so i just learned that till now he had 10 sex partners which kinda turns me off (dont know why it just does)

Besides that he is really caring and great and we get along perfectly..
