I still don't understand how could one accept gifts from a stranger who appears out of the blue, whom you hardly even know his real intent, and then perform sexual acts on him. when he is not even your type you are interested in. The way you present your case, it sounded there is a transaction going on somewhere, and revealing a bit of material greed coming from you. Don't and haven't you realized using gifts over someone is a form of emotional manipulation? There is no such things as a free and easy meal in this world, except gifts from real friends who buy you things because you really need it, not you want it. For there is a saying, you buy things what you need and not what you want. Need comes first, wants comes later. This is not too late to distangle yourself from this situation. You should return to him all gifts unused or unpacked, and pay him back what you have used and unpacked. In this way, he cannot say you are materialistic, or you will be labelled with derogatory terms. As such, he can no longer can have a hold over you in the future. Period.
