Sexual drive. HELP

Okay Soo my sexual drive is like non existent. I’ve been with the same guy for like 6 yrs and in the beginning of our relationship sex was great but now like I don’t want sex and it’s not him because.. I don’t even get turned on by porn. I’m 22 yrs old and i feel like I’m to young to be dealing with this. I honestly think is birthcontrol but I’ve tried 3 different types and nothing.. I feel like I should get an actual obgyn because all I have is a primary care doctor.. and I’m borderline thinking about maybe female viagra or something ... what do you guys think?? Is this normal??
