worst situationship.

I have been texting and a lil flirting with this senior from my college for around 3 months. and uh out of nowhere he hit me with 'not to offend but wht's ur bodycount'. I just stared at the text for 10mins. did not know how to answer it. i felt weirdly offended by that text for some reason. I somehow managed to divert the topic . cuz idk I felt that question was way too personal?? I mean I'm pretty comfortable with having no experience, but for some reason I did not like the tone of his.
any of u guys have been through smthg like this? feel free to share.
