See this is a common misconception
You arrange the first date as a possible bumsexual (as you so gloriously put it) but then you make it very clear on the coffee date that you are in fact a raging heterosexual.

By which time they're already comfortable in your presence.

I also find the "telling them you want to wait before sex" as the best way of getting sex far sooner than you first imagined.

Reverse psychology is great!
