Had now l opening is swollen shut---advice?

Ok so my husband and I got a bit drunk and had a couple hours of , which included quite a bit of time of him using his fingers inside me. I was understandably sore the next day. It is now 5 days later and after day #2 I started having some pain around my l opening. Day #3 the pain escalated and became pretty bad while sitting, walking, laying, wiping, if I even gently (and I mean gently) touch it, and I noticed there was a small amount of blood when I wiped. Day #4 (yesterday) was just awful. I did as much examining as I could stand, and noticed that my l opening is basically swollen shut. I had a little success with the pain when I applied some Neosporin with Pain Reliever. I could at least sleep better last night. I am starting to get really concerned because this is lasting quite a while and causing me quite a bit of pain, plus I was alarmed when I couldn't even "find" my l opening (like it was closed up, you could not get the tip of your pinky finger in there)
