bumps that arent herpes

i have keratosis pilaris and also we all probably get razor burn and ingrown hairs and all that...

i sometimes have little red bumps on my butt close to my genitals and im scared when i try to have sex with people who know i have herpes theyll think its herpes or itll just gross them out. this one stubborn bump wont go away and im sad. anybody else have this problem ??
