My boyfriend and I had a long discussion last night regard our sex life and the lack of communication. For being together as long as we have we don't know much about each other sexually. We usually have fairly vanilla sex. As we grew closer I told him I wanted more and he agreed. The problem was, it was all one way sharing from me. I didn't really know a thing about his kinks and turn ons. That is until last night, he realized it's been really one-sided and cited pleasuring me as his main source of enjoyment. The conversation went a bit further, he said he doesn't have as active imagination as I but when the thoughts come to him he'll tell me. He then told me how much he wanted to explore anal sex (receiving and giving) and that he wants to cum into my panties while I'm wearing them. I wanted to know more about what may have sparked this interest and other things in that realm he may also be interested in. However, I noticed most ejaculating into panties kinks were had by women. Personally, I've never even thought of this. It's intriguing and I'd like to let him but I wanted to know if any other guys had this interest and where/why it started. Regardless, I'm going to let him do it, I just wanted to pick some brains and learn more. What is so gratifying about blowing your load in your girlfriend's undies?
