I'm going to try and keep this post short and sweet.

I'm currently a 17 YO average guy, really. I'm insecure about my looks, but a lot of my friends and fellow redditors told me I look quite good and have a lot of potential. I'm a bit chubby (not fat) but it doesn't really show, I groom myself and keep myself in reasonable shape, but I have a problem with social anxiety.

I recently had an epiphany that everything that I've been doing so far (being a beta nice guy, not hitting on girls because of anxiety etc) has been stopping me from getting pussy. I am now in the process of reinventing myself and have completed some steps like finally not being a pushover and standing up for myself, but I am uncertain when it comes to girls.

Really, I don't know where to start. I'm not known as a weirdo in the school, but more like the quiet quirky guy, so I think I can start on a relatively clean slate with other girls. By stepping up my game I mean "finally start dating and having sex", but I am really inexperienced in this field. Honestly the only girl ATM that seems interested in talking to me is a 6.5 out of 10.

How do I proceed and, well, get good with the ladies (and get sex!)?

Note: please excuse me if the question is dumbly formatted or my writing sounds stupid, it's late where I live and I'm super tired.

ALL ADVICE WELCOME!
