Paranoid that Meds are effecting my sexuality

Hey, I'm sixteen.. and I've recently come to agree with myself that I am gay. However, recently after researching why it takes so long to climax.. I have determined that is was the anti depressants, and after looking more into it.. it effects a lot of things sexually.. so I started getting paranoid that I'm only gay because of these meds... because, I enjoy being gay.. Can anyone help me out here?
