Okay so last night my bf and I messed around quite a bit.. we had sex once and then messed around a couple more times. Well 6 hours had past since the last time he had cum... but when we got badk from a concert that night we attempted to do it without a condom for like 2 seconds... he had peed before this happened as well like maybe 20 min before...the head is the only thing that made it in and we had tried for less than a minute if even, I pulled away because I didn’t want to do it... I have the nexplanon implant though but I’m just worried could there be sperm? Cause he had cum 6 hours before... he peed before this happened as well idk if I’m being paranoid, can I get pregnant?
