My boyfriend had his penis in my vagina, but we only did it for a minute (at the most). I'm scared. Can I get pregnant? Please help.
Yes, it is possible to get pregnant from that. Men drip pre-ejaculate fluid when they are sexually aroused. That fluid can contain sperm and in theory it only takes one sperm reaching your egg at the right time to cause a pregnancy. The odds are low, but they are definitely not zero.
Can I get pregnant if the condom kept slipping but never fully came off?? He pulled out before he came just to be sure, but it kept bunching up, and I'm not sure if it's because the condom wasn't the right size or something else.
Any act of sex carries the risk of pregnancy, not matter what precautions are taken. You can reduce the odds, but you can't make it an absolute impossibility. In this case the question is whether any of his fluids leaked up the sides of his penis or not, which is not possible to say. The odds would be low, but no not zero.
But notice how you two are progressing in your sin. You went from a brief penetration to complete sex in just a few days. You worry about getting pregnant, but I am more concern about your soul. You are sinning and don't seem to be concerned about the consequences of that sin. "Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor homosexuals, nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God" (I Corinthians 6:9-10).
