Emotional contagion or mutual attraction?

I have a very specific type and two guys I encountered recently (not for sex or a date), I felt very nervous around as I was attracted to them. They both also looked very nervous and like they wanted our encounter to be over at the same time. But one of them also went red when I talked about something intimate. The other said see you later/ soon or something along those lines. No other signs. They just looked nervous. But strange how they acted exactly the same way around me. What could this mean?
