Booty Acne

Does anyone have tips on how to get rid of stubborn butt pimples ? I put tea tree oil on them. It's so annoying. My BF is a butt guy, so I get self conscious when when things get steamy :/ 
Could it be folliculitus ? I only get it on the bottom part where my leg and butt meet. 
HELLLPPPPP, can anyone relate ?
