boyfriend won't talk about losing his virginity

Becca
So my boyfriend and I have been together for a little over 6 months. I told him who I lost my virginity too, I didn't go into detail or anything but I told him. And when I asked about him, he won't tell me. He told me to not even ask again because he won't say to who or what happened. And of course that just made me even more curious. And now it is bothering me. I asked him if he still had feeling for this girl even though it was like 7 years ago and he said no. But I just really wanna know. Should I just drop it and hope one day he will tell me? Or should I ask him again and tell him that it bothers me that he won't talk about it? We tell each other everything and yes, we are sexually active (very). Thanks in advance. 💙
