Search Results: struggle to make any relationship work

The guy's almost 30 years old, with a Master's Degree and a relatively well-paid full time job. He's also 5'10" and weighs in at 80kg, with black belts in a few different martial arts, and considerable athletic prowess (runs 100m in 11 secs, 200m in <22 secs, javelin throw of 75m+). However, he's also a virgin, and has a near-total lack of sexual experience, having never had a girlfriend before or even experienced his first kiss before meeting the girl. He has epilepsy, so he's not allowed to drive. He also has mild Aspergers', which can make socialising a considerable challenge, as can the fact that he's a teetotaller, who's never drunk alcohol, smoked or taken any form of non-prescription drugs in his life. He's also only had his high-paying job for the past few months, and he's still struggling to pay back his student debts.

The girl, on the other hand, has only just turned 18 years old, doing an arts degree and struggling to make ends meet. She's only 5'4", and has a petite/toned build, weighing in at roughly 50kg. She also has decent athletic ability, though hers is more gymnastic orientated. However, she's moonlighting as a lap-dancer in a nightclub to help support her student finances, giving private strip-dances to paying costumers as per her work-agreement- though she's more than willing to ditch her night-job after meeting the guy. Still, it's safe to assume that she isn't a virgin, and that she has plenty of sexual experience. She can drive, and has a car. Thanks to her side-earnings, she doesn't have any debts. She doesn't smoke or do drugs either, but she has in the past, and she still drinks alcohol, albeit in moderation. And she's quite extroverted, having no problems with socialising at all.

If they were to give it a go, and embark upon a fully-fledged, committed sexual relationship with one another, which of the two would hold the position of power in that relationship? How so, and why?
