Hye

sorry, but i think maybe that was some changes happened after having sex for the first time. maybe the mucus was semen. and sometimes for the first timer our vagina kinda have some 'luka'. idk abt anyone else but i got some experience after my first time and when i want to pee kinda having some pedih there and also usually in morning after sex some semen will come out if u havent wash or pee before sleep. but if that situation of u continue should consult a doc. mine was okay after 1-2 days after that and rest for some time from having sex ya.
