What Could Cause A Unclustered Pimple Like Bumps On Underside Of Penis Shaft?

I have two small, unclustered pimple-like bumps on underside of my penis shaft -- one fairly close to close to base of shaft, the other about a half-inch away from the first bump. The bumps have a white lymphy center. I first noticed them after having vaginal intercourse with a woman with a condom. The woman has no known STD history. The bumps are not painful, but can be itchy. At first, I thought I could pop them, but only a very small amount of clear fluid came out, and lympy centers remained. I've had these for about 10 days, and they haven't gone away yet (although I have continued masturbated during those 10 days). The bumps have not crusted, even after squeezing them. I have not gotten flu-like symptoms since developing the bumps, although I did have a moderate head cold for a few days during the period. No painful urination. NOTE: I have recently had bad bouts of follucilits afer shaving in the groin area, and developed bad boils in the pelvic area. (I've been seeing a dermo about them.) I had also shaved the penis shaft before sex, but had not gotten boils in this particular area, I'm thinking the bumps could be lymphoceles caused by the condom-ring friction, or very small folliculitis boils. But does this sound like herpes?
