I had (still have) a long term male friend.
Nicest guy you could ever meet & he is attractive too, no doubt about it. There is absolutely nothing negative about him.
Friends always said we would make a great couple but we were rarely single at the same time.
We went to 3 dates, no issues kissing or anything & would end up in bed together just kissing or holding each other which was lovely but it was like there was just some sort of block every time it get passionate so we agreed to take it slowly.
Anyway 3rd date came and I was thinking "cop yourself on, it's not that weird, you are overthinking etc". When we were at literally the point of entry, I just went "oh God, I don't think I can do this, what if it's bad" and he went "thank god, me neither, it's just too frigging weird".
We just spent the night talking & trying to figure it out. There was attraction, we had both thought about it over the years, times we were jealous of other partners etc, do like each other but it just felt wrong.
I don't overthink things, & I've definitely had sex with way worse than him etc, but couldn't do it, not even just to scratch an itch. Still don't understand.
We both moved on and our partners are really good friends too & there are definitely similarities.
But nope it didn't and wouldn't work. Only conclusion is too long in the friendzone.
