Is this normal? Or is ok for me to be a little offended?

I met up with this guy for the first time for drinks, we're both in our late 20's. The conversation was ok, with a few exceptions. He asked or mentioned that he likes to have sex with the lights on and doesnt like it dark. For a first date you're telling me this?! I thought it odd. He asked if I looked good in a bikini and if i was confident in a bikini. (again...topics for the first meeting?) Then later he mentioned that next time I see him it would be ok to where something a little slutty or sexy with high heels, that he's not one of those men who doesnt like his girl to dress sexy. And im not sure how the hell we got on this subject but somehow he managed to bring up the fact he's had sex in public places and he asked me if i had. Is it normal to be a little offended by those comments?
