Pubic rash

[deepcoma]

Hello. I have a small red bumpy rash that hurts badly and has slight blistering or maybe scabs...can't tell. It has a tiny bit of watery puss and is only about the size of a quarter and doesn't seem to be spreading but is getting worse in pain and looks. I have had it about 3 days. In addition the lower sides of my pubic region on both sides seams swollen and hurts if pushed on even lightly. I have been getting pain in either what seems to be my bladder/ascending colon region best I can tell going on almost 5 to 6 months maybe longer. I have not had sex with anyone but my regular partner who is pregnant with my child and never leaves home without me so i know she hasn't either. I am the only man she's been with ever as well. About a year and 1 month ago I shaved my pubic hair off to impress a girl I had been sleeping with for about 2 months. It may have been a coincidence but 3 days after I shaved my entire pubic region had the same traits look and pain/itch this area has now. Is it perhaps possible that the first time was an outbreak of something and now this is the return? Or may this be a different medical problem? My muscles you use to goto the bathroom or sit up are also kinda sore maybe hard feeling. Any help would be amazing.
