unfortunately, i was stuck in my spine 6 times by the hospital's "top anesthesiologist" and it did not take. i ended up having a small injection in iv of some type of twilight drug that just made me feel drowsy. i tell people that i just had the darned baby naturally
what a mess that was
all i can say is for your boyfriend it perhaps was "out of sight, out of mind"...
i agree completely with what rockrose said. never have witnessed it being successful. for people who are supposedly in love to cohabitate, i believe they'd be better off making the commitment and vows to work through life together first because more and more often--they end up with kids
doesn't matter what position you're in, the condom does its job. it will not run out of the condom unless the condom tore, split, broke
