Dude, women love accents!! lol. Well, some of them may not, but who cares. James Bond has an accent, and do you think he'd be scared about talking to women?!
If you feel there's something that is not allowing you to succeed, simply work twice as hard to overcome that obstacle.
If an accent is worrying you, then learn how to speak slower and how to pronounce your words correctly. If you're not too tall, then go for chicks who are smaller than you. If your penis is not too big and you can't make her cum, then use your fingers!!!
My point is that don't let any minor challenges in life stop you from achieving your highest point. You control your destiny, you control the sets, you control your approach, your accent, the women you want...it's all about the right attitude.
Are they all going to be attracted? No, but no one is able to get them all anyways lol
Good luck champ.
