Why do people blush around their crush?

I do it mainly out of being nervous, though i'm not sure why I'm so nervous around her.Why do people blush around their crush?
lol i do the same thing, maybe its because u don't know how ur crush feels about u or how they're gonna react and u just feel insecure but good at the same time. its probably from all the pressure of love ;pWhy do people blush around their crush?
OMG, this is totally what the dude i like did! i went to his church and when he came in he blushes furiously and walks out the door again!!!! then he went and asked me to go skating with him.


i guess its because they know you're around and they are kind of insecure about the way they look.
This is just our biological response to attraction.





Pulse increases. Circulation increases. Our senses become heightened. It makes it easier to find a mate because we have a tangible sign that they are attracted to us.





When we are in a committed relationship our biological responses continue to reveal to people that can not have us that we find them attractive (and they can be flattered). But when we are single it is a blessing because we have a clear sign.
