Stink Down There

For the past couple of nights, I've been getting sweaty down there after I've gone to bed and it's been creating a very prominent odor that I smell whenever I lift the covers up. It's disgusting and I don't know what's causing it. I already wash with feminine wash but I've tried using a little more, I tried wearing Nike shorts to bed as oppose to thick pajama pants and both of those things haven't help. I even went so far as to thinking the fact that I haven't "trimmed up" down there was the problem. Did that and I'm still sweaty and stinky down there. Any advice or tips as to what could be going on???
