After two weeks? Absolutely not. If anything, he should feel slightly presumptuous. Mayhap a gift card is in order.
And just as a general rule, sex stuff shouldn't feel like a competition. If you're keeping track of how many units of sex you can score off your partner, you're focused on the wrong things. And your chances of nabbing a sponsorship deal are minimal.
Sex is, by nature, goal-oriented (moreso for dudes), but that shouldn't dictate the pace, or depth, of your physical relationship with your partner. And two weeks? All you owe a guy after two weeks is a friendly text should you suddenly move out of the country.
Which is not to say you didn't leave your boyfriend sexually frustrated, because you probably did. But if women felt the need to have sex just to prevent male frustration, civilization would cease to function and collapse in a pile of sweaty guilt-gasms.
"But if women felt the need to have sex just to prevent male frustration"...
Sadly, of course, many men do use this as a way to "score units of sex" off their partners (which is an immensely awesome phrase, btw). "Blueballing" and "cocktease" and "if a guy has an erection and doesn't ejaculate, his penis could explode, which would kill him" are all phrases used to guilt women into sexual activities.
Thank you for reminding us that sex is NOT a competition, nor some sort of commodity traded equally in "units" according to some tacit bargain.
I'm ashamed to say that "I don't want to die a virgin" was what got me.
