So my SO doesn't feel comfortable cumming inside of me even though I've been on BC for about 6 years now. I don't like condoms and we've been tested and everything. He just doesn't want to get me pregnant. He recently brought up the idea of using spermicide. I'm kinda uneasy with the idea of putting something up my vagina that is (I'm assuming) chemical based. Has anyone had bad or good reactions or experiences with spermicide?
