His motives

Okay so theres this guy who I known for 2 and a half years. Our friendship or like relationship is super odd, confusing, complicated and not normal. We never kissed or like did anything physically because hes so ughh idk how to explain but he does give me mixed signals tht not just me but others see it too..

My question here is what are his motives or a guys motives on asking me nonstop if I got laid or had sex. Like literally hes only the one tht asks me this. Im a virgin and im 22. He gets like weird and ike says things tht im wasting time, need to get some etc but everyother person guys too dont care.

Plus he brags on how good at sec he is n how every person he had it with told him or come bck wanting more or just a last tome fuck... but to me he doesnt do anything he just asks. Am I like missing the hint..

What do u guys think??
