Me and a boyfriend were kind of messing around on vacation. I as well as he were arroused but didn't want to have sex becuase i'm not on birth control and we didn't think a condom was enough protection from pregnancy. We were in a fresh water lake and he was erect..His penis started to rub against my vagina but i had a bathing suit bottom on.(spandex). The only reason for my uncertainty was that it was kind of a loose bottom and opened a little on one side when he was rubbing. With all the factors together such as being in water, him not actually penetrating me , and him not ejaculating could i be pregnant? Could the Pre-cum have gotten in my vagina? I'm trying to be as clear as possible and i need an opinion or answer. A pregnancy test is in the works to be sure..but not until after i miss my period.
