OK about 6 to seven months ago I had sex with a girl and a few months down the line I had got sevral bumps that were filled with clear liquid it got to the point it swelled up and itched vary bad to the point it hurt when I had to touch it to pee I've looked it up on sevral websites and I'm worried its herpes simplex beacause just recently I noticed that in that same spot on the shaft of my penis it was irratated and their was a bump now I left it alone and it cleared up so I wasn't going to worry about it the other day I had sex with a different girl and the next day I noticed I had a rash in my pubic hair with little red bumps and on my inner thighs there are bumps that look like pimples with a white head that form in a line but not touching each other and they also itch badly I'm really worried I gave my girlfriend something serious how can I tell if its herpes simplex the genital type?

Go to your doctor and have him diagnose the problem.
