We’ve been seeing each other for about 6 months and are very close. Sometimes he comes in me (I’m on birth control) but he always pulls out after. But this time I was on top and he came and I tried to get off and he wrapped his arms around me and kept me on top of him and his dick in me for 5 minutes and wouldn’t let me get up. I had no problem with it he just has never done that. Why would he have done that?
