Not every guy knows how to give good oral (in my experience most don't - and I'm talking older, experienced guys). If you can get yourself there, and he can't - it's pretty clear where the problem lies.

He needs to use just the tip of his tongue on your clit (presuming he actually knows where to find it). I don't feel any wetness from my man, but the sheet is soaked underneath me from where his saliva has gone (if yr mouth's open it's gotta go somewhere).

Don't beat yourself up about this, when you find a guy who has the expertise, you'll love it!! It's up to you whether you talk to him about his technique, or whether you move on to greener pastures.
