I have no idea about a hair follicle specific HIV rash, but to be sure about the HIV you should be tested. Most Planned Parenthood clinics offer the test at little to no cost and use a test which gets the results in about ten minutes. Shaving definitely can cause a rash similiar to what you have described.
For your own peace of mind, GET TESTED. Remember that no matter how well you know someone you don't always know everyone they have been with. You are putting yourself at great risk by having multiple partners and not using protection. Planned Parenthood also has free condoms, so pick some up if you go there for the HIV test. I have been told that the virus can take up to three months to be detected, so unless it has been more than three months since the last time you had unprotected sex, you may need to go back later for another test to be sure.
Don't rely on others to protect you, protect yourself always! Good luck and I hope everything is okay.

No, HIV rash is not specific to stomach area or to hair follicles. This could either be an allergic reaction to the shave—the things used for it or it could be a skin infection called cellulitis or it could be infection of hair follicles. Test for diabetes as this precipitates all this. Also if you had multiple partners, then go for a complete STD panel. A dermatologist can confirm this for you.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
Im not sure, but could it be Herpes. You need to have a VDRL panel done with HIV testing. It will check for all possible STDs. Hope everything turns out ok. Im sorry that I couldn't be of more help.
