Sexual Fetishes

Ok so My daughters father was my first and only sexual partner and now that we have split up I have dipped my toe back in the dating pond! I have noticed several guys with different fetishes however 2 stuck out and I am alarmed but I am trying to having an open mind. So one guy loves bigger girls even told me at 245 I wasn't big enough. He also said he has a thing for pregnant women! So I guess I'm asking is the pregnancy fetishes a thing or does he have issues. I am very sexually naive and not sure what's normal or weird!
