So me and my sex buddy have hooking up for a year. Two months ago I found out that he keep track of my cycle and ovulation time. Lately, he is being doing some wired things, like trying to having sex with without a condom or begging to come in me knowing very well I am ovulating. I am finding all of these to be a little stranger. Oh and last month when my period was two days late he make a comment about if I was pregnant it will be great that he I I’ll step up to so what is right. But the funny thing is we are not even boyfriend and girlfriend and I don’t want to get pregnant yet. WTF is wrong with him
