I had unprotected sex for the first time today. The guy I was with ejaculated an hour before we had unprotected sex. He says he whipped off the leftover cum with his shirt so he had no pre cum and he never came inside me because he has great self control

Anytime you have unprotected sex, there is a chance of pregnancy. However, if your partner did not ejaculate inside of you (or near, on, beside your genitals), then you would not have a risk of pregnancy.

Your partner ejaculated prior to having sex, then wiped off the ejaculatory fluid from his penis with his shirt, in order to then have sex with you. I hope this is all OK with you, as it is not painting a very good picture in my head as far as how you are feeling (perhaps just the wording; I just want to make sure you are emotionally OK). If he wiped off all the sperm off of his penis, then there would be no chance of pregnancy.

Please have your next partner use a condom anytime he is near your genitals, as there just are too many factors that could cause him to ejaculate inside of you (no amount of "self control" can help if the man is distracted, in a sexual position that is difficult to withdraw his penis in time...the consequences of him ejaculating inside of you, whether or not he thinks he has superman self-control is not worth it). Please don't let any guy talk you into having sex, or even making out, if his naked penis is near your naked vagina without a condom.
