Suggest Treatment For Vaginal Pain During Intercourse

I recently had intercourse with my boyfriend. Neither of us have an STD (we've both been checked) but since then i've felt a lot of pain in that area. It doesn't really effect me too much as long as I don't wear tight pants or touch around there but it burns when I urinate. I don't know if I tore something or just got a severe "skin burn", I guess you could call it. I'm hoping it doesn't last much longer because it is extremely painful but until then, is there something I can drink; water, juice, etc, to help reduce the pain when I use the bathroom?
