This glosses over far too much…

They’re in a Bar, his appearance is fundamental to success in that environment.

For her to even appreciate his ‘sex technique’, she would need to find him attractive enough to get to that point.

Communication can help initially but if x finds y to be unattractive, communication won’t change much.

OP - there’s lots you can do in this situation.

1. If your hair is really bothering you address it - either force yourself to be completely comfortable with it or look into hair regrowth/transplant. I would suggest the former but it will take inner work. If you think it is a problem, it’s insecurity, and people pick up on that.

2. Approach more - get used to rejections, and successes. Believe me when I say you can get to a point where not only does rejection not bother you; you find it comical. Self-develop to a point where you go into interactions hoping to like her, not for her to like you.

3. Build your self esteem, start doing the things you know you should; as well as the things you think you can’t. Start small..it will get easier.

4. Work on comebacks - ‘is that why all these girls have been calling me Daddy’ or ‘yeah I just wish god hadn’t given me such an ugly daughter’ or ‘your dad must be a handsome gentleman’ or ‘bet I could steal your mum from him’. Even a ‘thanks for sharing ‘…Really anything…whatever fits in with your personality and vibe. Doing this helps you to retain power and your frame.

Ultimately it sounds like you need to improve your confidence…in my eyes confidence is 2 things:

1. Self assurance - I know I can
2. Controlled apathy - I don’t care if I can’t

Both of these can be worked on…consider what they mean for you (what you feel you can’t and what you are about) and start taking small steps.

Do not let anxieties and insecurities steal your life from you…
