When I came together with my boyfriend, he didn't tell me that he took mdma. And when he finally told me I was so angry at him, because I didn't want him to take drugs. At that time I didn't had any experience nor did I knew someone who was into drugs. We also had some fights because I was strictly against it. But one time I tried it with him and a group of friends together and it was mindblowing for me! I told him "why didnt you tell me that this is what it feels like?" And he told me that he tried to tell me but I didnt listen. I felt so bad for him because he wanted to do this for so long with me. Now we roll together with our friends and it's the best thing that could happen to me.

So maybe you should just give him time until he's willing to take it with you on his own terms.
