Poll: Is this a good ice breaker at the start of a date?

You need something modern and relevant like...
"Are you infected or carry the antibodies?"

i think it is a good one

More successful is to say "Hey babe, wanna fu ck?  By the way, how do you like me so far?"  It get's her laughing, which is always a good start.  

Sure, anyone who cares that you made a little error is ridiculous.

Hi There! 
Yes it is my darlin' 😃 💋 !

My opening line is always “Hi ! I hope you are not on your period, because I will be wasting my time, as I hate blood”

Sounds fine to me.
