Lmao.... Internet has made us very conscious when we shouldn't be. Good luck op. Fact that you are "performance concious" means you're good at it but don't be too hard on yourself.. specially when you're dating nonstop.
Some chicks like to get attention in front of their partners.. specially hot chicks. It's an ego boost for them and you didn't do that. She must be used to a lot of attention which she did not get from you. This can make them uneasy. That's why this probably happened.
If you're 6'5" and posting here with these queries you need to rethink everything and come back with a plan on everything. Me: 5'7" and always thinking... But you shouldn't.
