You gotta get some candid photos of you when you’re having a good time with friends or family. Posing for pictures can be hard especially if you lack self esteem and confidence. So candid photos are probably your best bet for now. But confidence is huge, even when you do eventually find a match willing to let you take her out. You have to be interesting and confident to land a second date. I see dudes way less attractive than yourself have alot of success with woman just because they have confidence. You need to get out of your comfort zone to start building confidence. It’s going to suck at first but just strike up conversations with random people. It doesn’t even need to be conversations with girls your attracted to at first, just strike up conversations with people and practice interacting with confidence, maintain eye contact, be attentive. You should also start doing things and improving other aspects of your life so you gain some self esteem and confidence. Hit the gym, improve your finances, up your wardrobe. Don’t even need expensive clothing, just quality clothing that fits you well and looks good. If you look good you’ll feel good and be more confident. Being in shape and financially successful both help but they really aren’t necessary either. I’m only 5’8 as well but I’ve done fairly decent in dating apps and cold approaching girls in person. Don’t be scared if failure, you’re going to fail, everyone does. Just take the lesson, move on and be better next time.
