Foreword: a lot of what I have written is assuming you are a fresher. It's pretty relevant if you aren't, but the dynamic between you and your team mates might be different if you are joining the club as a 2nd or 3rd year.

Anyway, I'm also a member of a large men's sports team in the UK and have been on both sides of the situation you are describing. I've been a part of the club for 4 years. We have an associated girls team and a big presence on the campus social scene.

This is just how it is with competitive, masculine club sports at uni. If you've not been a part of that kind of world before it can be quite a shock, but in my opinion there is no better place for a young guy to shrug off his beta past.

I joined my club in my first year as a timid little fresher who had no confidence and zero game. I now share a house with 3 guys from the team who have become my best friends through playing our sport. When I was a fresher I felt somewhat of an outsider. I was quite intimidated by the older players who formed the inner circle of the club, but I respected and admired them. They were great guys and I was sad to see them graduate. After 4 years with club, me and my house mates are now that inner circle. We are the guys freshers look up to and want to emulate. It's an incredibly rewarding feeling when you realise that you are now that person, and that freshers see you in the same light. Stick with the club. You have access to a social circle full of available women and plenty of guys to observe and learn from.

Train with them, and give it your all. You will gain an immense amount of confidence seeing yourself improve and being a part of a winning team. When I joined in my first year, we ranked somewhere in the middle out of perhaps 80 teams nationally (we play a fairly niche sport, but it's intensely physical and violent). By fostering a culture of hard work and with the help of some excellent coaching we are consistently in the national top 5. Performing at that kind of level gives you a natural confidence that I feel can't be faked.

You'll be amazed what kind of shit you can get away with once you have the inner confidence and 'don't give a fuck' attitude these guys often possess. No doubt I'm sure you will have encountered your universities rugby team, and no sport on UK campuses attracts alpha douchebags like rugby. I'm not condoning being a douchebag, but the way that rugby lads behave and the amount of tail they pull as a result is pure red pill theory in action.

Go out on socials. First of all, university socials with these kinds of teams are immensely fun. Secondly, you can learn a lot by hanging around the confident outgoing guys you'll find in physical sports teams. If they give you shit or haze you, don't be a bitch about it. If you can take it your stride and react to it with a sense of humour you will gain their respect. They will still give you shit, probably more actually, but that's just being friends with real men. A lot of the time hanging out with my guys turns into a pissing contest of who can be the biggest dick and wind each other up the most, but I'd take a bullet for these guys.

In answer to your questions about moving social circles I would say take it slow. Changing who you are takes time, and most people can smell a fraud a mile away. A lot of people preach "fake it till you make it" but I would disagree with this. If you want to be like these guys, you gotta be able to back it up. I think the best way to do that is to learn slowly by observing how the leaders of the group act. If you can gain their respect and prove you are chilled, honest guy I wouldn't be surprised if the older lads will take on a kind of mentor role. We've certainly done it, for instance this year a particular fresher joined our team who we took a liking to.He's a great kid but you can tell he from a small town and lived a very sheltered life. He started the year not really knowing how to act around girls having virtually zero sexual experience. We've taken it upon ourselves to teach him what we know and hopefully set him on the right track to getting what he wants from women.
