Me and my gf were making out yesterday. We completed the act once using a condom. Now the second time she gave me oral and with flow she rubbed the saliva on her vagina. I started fingering it and realised will it be safe to do so. I am quite sure I did not ejaculate till then (second time) but is it possible that some of the sperms from previous act may have stayed there and may have gone in her mouth with pre cum (i do not remember urinating in between). Her periods are due this thursday. We were thinking of taking an Unwanted 72 to avoid any doubts. But that may have side effects and its difficult for me to see her going through that. Please help me out here I am freaking out over this issue. We do not want to get pregnant at this point of time since we r just 20. Please help me out here.
