different people have different methods, ^ i could never do what he suggested but mr. numbers understands girls. the blindfold thing i can pull off, it wouldn't be great but i could do it but if OP's girlfriend needs him to make her feel special i doubt he could pull that off. the blindfold thing you've gotta have good socializing skills or else you might come off as a creep if she's not comfortable with you. i mean she is blindfolded, BLINDFOLDED! the possibilities are endless. the nervousness could come off as cute and that you're trying, but i fucking doubt it.
that being said, if you make an ass out of yourself in the
right funny kind of way then she'll be more at ease with you. just make moves as you go so you don't end up becoming her friend after, not into her pants (yet

) but by her lips. mind off the prize, in the end you usually get the prize.
"make me feel special" is that womanese talk? does she want to be walking on the red carpet at your expense? being driven around in a lamborghini? if these dinners you and her aren't cutting it, and you and her isn't special enough anymore than jokingly tell her you'll be more special when she's more flexible, not the sex position kinda flexible.
you told her you were going to surprise her next week? where the fuck is the surprise in that?! when you're predictable as an open book and available they lose interest. maybe she's losing interest.
