after sex w/ my SO pulling out there is white cum inside at the very end of the condom he says its me &’ my cum.. im pretty sure the condom didnt break because i squeezed the tip of where the semen was like every other time for no holes but if its my cum at the very bottom of the condom i cant get pregnant right? if i put the condom on correctly w/ a little air at the tip i should be fine? &’ it was definitely my cum at the end too right..his precum showed up at the tip of the condom before in previous times before he pulled out &’ came but his cum cant get so low down there ? im just scared &’ hoping it was me & not him. has anyone else experienced this? this white substance inside the very bottom of the condom? my birth control is condoms &’ i know how to apply a condom right i just want to make sure im fine
