Is this a wart? Herpes? ingrown/pimple?

Hi everyone,

I noticed this spot on my balls 2 days ago which had small white head. When i squeezed it small white puss similar to a face pimple came out (very tiny amount). It also hurt a lot when squeezing it.

I am wondering if this is something i should be worried about?!

I put tea tree oil on it to see if it will help. Doesnt seem like herpes to me or a wart but i am planning on having a threesome soon and was wondering if i should cancel it.

Thanks,
