very low to nonexistent sex drive

Hey ladies! I am currently on lexapro, adderall and the birth control implant. I just switched to the implant two weeks and before that I was on the depo shot. My boyfriend has been complaining because I never initiate sex anymore. I think my boyfriend is the sexiest human to ever walk the earth but I just do not get horny very much anymore. Sex feels more like a chore to me now.. I have trouble getting wet when we do have sex. He's amazing at sex... it's just very hard for me to feel pleasure or experience an orgasm anymore. Idk what to do.. this is so frustrating. Any suggestions on what could be causing this & what I can do?
