As a human being you are going to face social friction in every aspect of your life from one scenario to another.
Part of being an adult includes learning how to manage those frictions effectively from an internal and external view; you'll never hide away in a cave away from all human contact.
The professional and social worlds are more aware than ever, and more sensitive than ever, to those situations. Employees have more support than ever if a bad situations escalates to the point of needing support.
a few rather disgusting stories about men in IT and how I need be careful working in tech. I know it's a very male heavy environment, and that's fine, and I expect there will be a few men being perverts
This isn't an IT issue.
This is a human-to-human issue. In particularly you seem focused on men sexually harassing women. I won't say that it doesn't happen anymore - but culture has radically shifted in such a way that it is much more likely that professional men will ignore you like the plague because they don't want to risk their career and livelihood over ill-perceived improprieties because of an autsitic, failed social interaction. [And who could blame them, they are judged as disgusting perverts before they even meet their new coworker ;) ].
You have other social frictions you should be worrying about too;
How do you deal with an angry and upset customer chewing your head off over the phone?
How do you deal with a pissed off manufacturing supervisor, or sales person, that can't do their job because their IT system is down and you're the one responsible for fixing it? And they are losing $50k per hour of downtime? And executives are joining the P1 Bridge asking you how the resolution is going?
How do you deal with a hardass manager setting unreleasitic project timelines, and giving your poor performance reviews?
How do you deal with a business partner setting impossible, out of scope project requirements?
How do you endure the questioning on the Problem Management call when the best RCA you can provide to the system downtime is 'Idk it just went down, I rebooted it and services were restored"?
How well do you deal with Cathy who is old, ugly, and bitter and hates your guts and spreads rumors about you in the office because she thinks some Owner\Manager\Director shows you favoritism for being young and pretty?
Quite frankly calling IT men perverts is kinda insulting to the men, and that mentality is never going to prepare you professionally for a successful career. Broaden your thinking professionally to prepare for the roles and responsibilities of your new job; and then if you have any personal conflict with any coworker of any gender for any reason, escalate it to either your Manager or to HR if you ever feel like it's necessary - there is almost no scenario in the coporate US where you will not get support.
