should i feel guilty

last night around 10:30 this guy that i’ve been talking to came over. i snuck out and we sat in his truck. One thing lead to another and i ended up sucking his dick. i really care about him and making him feel good genuinely made me happy. I had never done it before and he said it was good but he didn’t come so i feel like he just wanted me to feel good and not be too down about it to try again. i don’t feel guilty at all but i don’t want to tell anyone so maybe i do and don’t realize it?

Btw i’m 15 and he’s 18
