Some mongers do tend to go overboard with their attempts to impress these gals...and such a desire to impress often belies deep-seated insecurities they have about their value in the eyes of women.
However...there are some benefits to taking steps to impress these gals.
It's an important precursor to fostering a greater sense of chemistry between you and the gal which will increase the odds of you accumulating the type of memorable experiences that supersede those where you're simply jacking off on your toilet like some poor bastard.
Since this is a thread about a GGR gal, I would take Kim's advice on how to approach this hobby (she left it in a Tori thread). If your sole intention is to get off without appreciating/ respecting the other human being, then you're better off investing in a blow-up sex doll.
A lot of mongers don't actually know how to handle women, and it's not really their fault, they're simply emulating what they see in porn.
