Lost my virginity

Hey. I'm 16 years old and I lost my virginity recently.. My brother had his friend sleeping over and they were drinking.. Btw they are old 16/ 17 yr olds. And I liked my brothers friend so he came to my room and we were talking then he just kissed me and so I did the same and he started to rub me n it felt good so I rubbed on him then gave him a blow job then he ate me out.. We also had a condom and this was his first same as me we had sex it hurted also my brother walked in on us but luckily he was to drunk to remember Anything.. Is this a good thing? A perfect time? We still talk but he moved to Oregon.. Can it be true I still miss him? Or am I just craving for more sex? I'm not on birth control or anything
