Yeah, that sounds like the best way to go about it. I'm kind of shy and tend to only fuck people I have an emotional connection with, so I'd kind of be stepping into the unknown using tinder the straight-forward way I'm probably supposed to, lol.
if you're shy and only fuck people you connect with emotionally then you're gonna have a harder time finding these men.
let's talk about the shyness. being shy is not going to help you get a big dick. you're gonna have to be at least assertive enough to ask for a big dick, literally. just tell every guy you meet that you're looking for 8+ inches. yes, you'll be knocking at least 95% of the men out of the selection pool but you said you wanted a big dick and this is the best way to filter them out from the get-go. no disrespect to the men who are under 8 inches but if that's your requirement then so be it. it would be the same as if a guy said "i want a red-head"... well, that just knocks out 98% of all women since only 2% of the world is naturally red (and that includes guys). you get the idea... shy = no big dick, sorry. first be assertive then be demure afterwards.
emotional connection? this one is even worse... so basically you're wanting to experience a big dick but want it attached to a man who can be and also considerate enough to connect with you at an emotional level? does that mean the meet-and-fuck option is out the window? you're asking men, who are already in the minority, to connect with you and put time into you before you will give up the bedroom time? that's asking a lot when you just want to experience a big dick.
why not try looking up local swing clubs to you. single, unattached women are always welcomed for free and without much hesitation. again, when you go to these clubs, just ask for a big one. some clubs will frown upon this as it is an act of inequality but i'm sure there are plenty of members with big dicks to feed the needs and curiosities of women. trust me on this one (i can't count how many times i was fetishized by women who wanted to be with an asian guy with a big dick).
good luck! of course there's always a plethora of men on this site who can assist. just fine one who is in your area that you can connect with.
