You need to define blind date. Have you:
1. Never seen or talked to the person
2. Talked to (phone or text/online) but never seen
3. Seen a pic but never talked to (tinder?)
4. Seen pics and talked to (match?)
So I have done probably one or two double date kind of things like 1. in high school where a buddy has a date and says hey come to this football game or party or whatever and meet her friend, but nothing really serious.
I have done a lot of number 4 cus I was doing the online dating thing for a while, way before tinder and insta date stuff, like 2007-2009. I was on match.com mostly, I probably met and went on a dozen or so dates, but only two girls did I have more than one date with. Most were just a lack of chemistry/attraction that you can only tell in person.
One girl I ended up going on probably 10 dates over a month period but things got really weird when I tried to kiss her. I found out she was a virgin which was fine, but she was really skittish about any physical contact. We were both 21 or 22 but it felt like we were on chaperoned dates in middle school. I didn't want to deal with that so I kinda stopped talking to her as much and she also withdrew, I think she just kinda realized she didn't want our relationship to go any further, I think she wanted to be in the friend zone or something. It was really weird but just naturally dissapated without any drama.
The other girl I went on multiple dates with is my wife! Yes we met on match.com. We chatted online for probably a week and then decided to meet at buffalo wild wings. We hit it off right away, she was so cute and funny, and I canceled my match account a week later.
