Sex is just sex.

Recently i had sex and i didnt feel anything. I mean it felt good but it was like omg yess....i didnt get attached or feel any connection with the person afterwards. This is only the 2nd person ive ever had sex with. When i had sex with my ex its like i was so craxy about it and attached and always wanted it but now im just like ehh. I like it i enjoy it but its nt anything special. This is only my 4th time ever having sex. Is this normal?...
