Anyone know what this is....?

So I got waxed over the weekend, and I usually put this cream on after that prevents ingrown hairs and stuff like that. This time I didn’t do it and this popped up about two days after me and my boyfriend had sex. It hurts a lot to touch it and white stuff was coming out almost like a pimple?? Is this an ingrown hair? I’ve never had one so i don’t know what this is or how to take care of it and make it go away??
