am i over thinkingg

mira
so yesterday i lost my virginity to this guy who i am head over heels in love with, i take sex as a very personal and special thing and i him being my first was a very thought out planned out decision for me. i don't regret it. but after we actually had sex i had to leave because i was going to go somewhere w my mom so we got up n were putting our clothes on and i started walking towards him and the door and he kissed my forehead but acted weird when i hugged him. and he msg me and asked about it but im not sure if hes nervous to talk to me now or just is being normal and im being weird. am i over thinking or is something wrong
