Okay, I'm going to try to keep this as G-rated as possible. My girlfriend and I are very physical. Sometimes it's oral and sometimes we have sex. The problem is, when we don't have sex I like to "prove my manhood" by being able to provide an ample amount of semen (either into her mouth or onto her chest). So to do this I don't masturbate for a while. The dilemma is that when we have sex the amount of sperm doesn't matter, it's the amount of time. So to do this I rub a few out before hand so I can last for hours (which she enjoys).
I don't need help solving the dilemma, but does anyone else have this problem to masturbate or not to masturbate? It's really a guessing game for me...I'm not complaining at all, I was just curious.
WEeEeEeELLL....first of all I'd stop getting off for a few weeks, faking sick.
Then, after purchasing flood insurance to some degree, I would suggest bringing her upstairs and showing off your "manliness." Or perhaps you could turn off the lights claiming it's for "mood enhancement," while slowly and stealthily connecting her mouth to a large garden hose. Wait the conventional two minutes, then turn it on full blast. It will probably throw her halfway across the room. (Chicks LOVE that.)
Also just out of curiosity why are you coming on her chest? I wouldn't expect a trunk full of old clothes covered with seminal fluid would be much of a turn-on. But then again the female mind is like the process of making cheese; we know nothing about it, and probably wouldn't want to.
I hope this helped. I do what I can.
Peace
