What are these blotchy rashes I get on my body?

From time to time I get these small blotchy pink rashes on various parts of my body. These rashes are flat (not raised), and completely painless. They do not itch and sometimes the might burn very slightly only when I take a shower and the hot water touches it. These have occured on my upper leg, lower legs, stomach, back and shoulders.

I thought maybe it was possibly herpes since I've had a few different sex partners, but I have had 2 blood tests for herpes that both came back negative. And I've never had blisters on these spots (although I know it's possible for herpes to not blister). Also, these occur in different places, not in the exact same spot over and over again.

Can anyone tell me what this might be? And by the way, these spots usually disappear completely between 1 and 3 days.

It could be prickly heat.
