I Haven't Sex For The Past Two Months. But Had

I haven't sex for the past two months. But had been masturbating a lot at lease 5 times a day for 10 minutes. I find one lymph node on my inner upper left thigh near my sac. It don't hurt. I had it for three days now it's going down. Now I think one coming on my lower left side on my neck. This one hurt when I move. I stop masturbating when I find the node on my thigh.
