Too much oral sex!
Now there's a problem most women would love to have...
First off, have you talked to your husband and let him know that this is too much for you? That you need a break. If you don't feel like playing, don't play.. there's no law that says you have to let your husband eat your pussy whenever he wants. Remember communication is key here. I realize he obviously loves giving oral pleasure, but it sounds like he needs to find some other constructive things he can do with you to give you and him both pleasure.
Basically, you are asking the same question many couples have asked.. where do we find the elusive single female. Maybe instead of looking soley for single women you should look for other married couples in similiar predicaments.. maybe she wants more than he can give and needs someone to help satisfy her while he watches. You and the other male can sit back and relax and enjoy watching your partners pleasure and be pleasured without feeling like you have to be part of it.
