Achiness

So it was mine and my boyfriend's 1 year and he stayed the night with me. We woke up and I was super turned on, my vagina was feeling like achy because I wanted him to be in me so bad. So he got me off without penetration first, but it just made the achiness worse, so we had regular sex, and after it I felt a little better, but the achiness is back and this time I'm not like super horny. Anyone have any ideas of what this is? I've also noticed my vagina has been really wet lately, like more than usual
