Hello,
Although the symptoms are suggestive of folliculitisbut other possibilities like genital warts, molluscum lesions and cysts also need to be evaluated. Moreover for the greenish discharge, Chlmaydia needs to be ruled out. For that get a complete STD panel testing done. Till then, keep the area clean and apply some topical antiseptics. Also wear loose-fitting cotton clothing and use an antibacterial soap or mild soap like dove. Avoid any kind of cosmetics. Topical antibiotics such as mupirocin or neomycin containing ointment are also useful. In case the symptoms persist then oral antibiotics may be needed. Please consult a dermatologist in that case.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I would like to add that upon reading several things I forced myself to ejaculate to check the color and it is a greenish yellow and is very thick.
