Wow!!!! You’re a woman with a high libido. In spite of all the sex you’ve with your husband every single night I’m surprised you still desire more at your workplace. Rather than calling it ‘sex for work benefits’ call it both pleasure and work benefit’; pleasure for you and benefit for your work/profession.
Since you said you’re still continuing your escapades with your customers, I suggest you land one of your customers at your house as well, because of the absence of your husband. I presume the personal reasons you mentioned for staying apart must be the fact that he got a hint of your cheating behind him, so if this is the reason, I suggest you decide right now on what exactly you want.
Is it sex with any random guys or your marriage with your husband where you also get to enjoy sex with him? If you’re having sex every single night with your husband, I don’t see any reason why you shouldn’t have sex with him whenever you feel the need. If he has no problem giving it to you every night, I’m sure he has no issues doing the same in the mornings as well, so think about it.
As for your abnormal desires, you cannot keep having sex when ever you get horny. Try to have some self-control over your mind. If you keep continuing the same people will start calling you an insatiable slut. Try to control your desires and also try to revive your marriage which I think is falling apart because of your cheating.
Develop a new hobby and try to distance yourself from this sex obsession for a few days. Try to abstain from it and see how you’re holding up. It would be difficult in the beginning but once you tae control of your desires, you can command them at any time you so desire. If your desires reach the top, pleasure yourself with the help of a dildo/vibrator or your fingers.
