Guy friend interested or just wants to sleep with me?

I have a guy friend whom I caught up with after a few years. He asked me how I felt about him, and he said he’s “interested” in me and wants to go with the flow, feel each other out and see where things go. Hw also said to promise him we’ll still remain friends if it doesn’t work out. Could he be sincere with me or just saying that (He knows Im a virgin)
