My boyfriend and I had been together for 2 years.. we had sex without a condom today. I sucked his penis and he cummed into my mouth but I quickly moved back to spit it out (I thought it was nasty) and he was still cumming, it got onto my shirt. Then, he put his penis back inside me for a couple sec... can I get pregnant? Did all of his sperm come out before he entered me again?
Yes you can get pregnant.
No, not all the sperm came out. There was semen in his urethra. Just inserting his penis would squeeze any semen out (with sperm) and into your vagina.
All it takes is one.
Hope it helps.
