Have you had sex before? Are you already in a relationship? Ask him, and try to communicate better. Don't do sneaky tests on him if you respect your relationship with him. Also, do you like this man? If you feel uncomfortable, I think you should back out while you can. The fact that you even have to ask this question gives me bad vibes. On the other hand, he might actually love you for you. As I said, your relationship will only go on properly if there is TRUST and communication.
