First off, don't scratch them!
Secondly, pimples sometimes are just that - pimples. If you are concerned, be seen when you are symptomatic. And of course, if you've never been tested for herpes, now's the time while it's on your mind. You'd want an IgG type specific blood test. Consider a full STD screening, so you can move forward and know your sexual health. If you have a regular partner, he should be tested as well.
Also, I only had sex with the 2 other guys once each, separately of course.
"When I scratch them, they bleed and they are not clustered together like I have read they usually are."
When I say like I have read they usually are, I mean herpes clusters
