So i had unprotected sex

I had unprotected sex with my gf and it was our first time. First we started with the condom but we removed it because i struggled to put it in, I didn’t really have an erection (horrible performance) and i didn’t cum inside of her and before having sex she gave me oral sex . I masturbated the day prior and peed a total of like 5 times before having sex and i cleaned my penis well. We did it on aug 2 and her cycle starts around the 20th of august. When changing position we engaged in oral sex (which i guess would also clean out any sorts of sperm or precum traces if there were any?) and i cleaned it with a paper towel before putting it in. I got an erection inside of her but i’m pretty sure i didn’t cum in her as i came after we had sex. My sperm is also very watery and clear which i guess is also a sign of lower fertility. Am i fine? Btw its too late for the pill
