My First Time Experience!🤦🏽‍♀️

So my first time was horrible and uncomfortable. I decided to have sex because I felt like I was missing out on what my friends were experiencing; Talk about peer pressure I guess. So I was talking to this guy and I texted him “ hey do you want to have sex?” He replied “yes” but he was already asked me for nudes and stuff like that so I knew he was going to say yes regardless. In someway I regretted the fact that it with that guy and the fact that I wasn’t in a relationship with him. Anyway I told my mom that I was going to have that weekend I was going to have sex. my mom asked me if I was ready mentally and I said “yes” thinking that I was ready. So while my mom was on a business trip that weekend u went for it. I did not have sex in her house I feel as though that is disrespectful. So on Saturday, I drove over to his house and we got straight into like kissing and touching in the back of my car. So I gave him oral sex and he came but he got soft and couldn’t get it back up. So I told him to get out and I left disappointed. When I got home i kind of freaked out and called my friends and told them what happened. So they told me to go back later on that day. so I texted him and I said: “hey I will be back later on so we can actually have sex”. He replied, “OK just give me time”. I gave them the time and I drove back to his house. I told him we should have a quickie and we did and I was very uncomfortable and scared. I felt like people could see us in the car and I was turned off in general. when he finally came I said “well then” and Asked him “please can you get out my car?” And he did. After that day we never talked again. I literally cannot face him again it was the worst experience of my life and don’t have sex just because your friends are; it’s not worth it.
