I've always had a mouth on me, I'll credit my dad for putting a very competitive drive in me from early childhood. But I was also pretty good at holding my anger and frustration in, and letting it out in my own way, by myself, before T.
One of the first mental changes I noticed in the first few months of T, was patience. I've never been a really patient person, but after T, it definitely sky rocketed. After almost a year on T, I've learned to quiet myself in my head, and just talk myself through it, silently, but it's hard sometimes no doubt.
I have a pretty tight relationship with two bio males, whom are twins. We are known to party pretty hard on the weekends (I've been slowing down in the past couple months). But months 3-6 on T, we'd get drunk, and box. I got boxing gloves from an old neighbor, and we quickly put them to use one night. I'm 5'4 150-160 (depending on the month) and my buddy is about 5'9 220. I got the first hit in, and it set him off real quick. Granted I was pretty intoxicated, he kicked my ass. I woke up with the worst headache/body ache ever. And it fueled me to one another go. Sure enough, a couple weeks later, we had a little party, and me and another friend went at it. It started out friendly (he's a gay queeny boy), and told me "no face shots". He was my size, a little heavier, and hit me in the face once, it set me off, and I pumbled the crap out of him, until he shouted STOP. I stopped, and in that moment realized I needed to relax. I really got caught up in the moment, and forgot for a instance, this is my FRIEND. What started out as fun, turned into an all out brawl, and it truly bothered me. On a side note, I decided after I have top surgery, I'm gonna get into boxing. It's a great stress release.
I know a lot of T guys deal with more anger/agression, and for others it "calms" you, everyone is different. It's how you learn to deal with it, that matters. I've always been a very competitive person, and enjoy a good fight, but not in a animalistic way. My aggression has definitely tuned down the past couple months, but I defitenily don't put up with ANYONE disrespecting me.
I work in retail, which sometimes feels like HighSchool. Considering the age range is 18-28. I work in close corters with one girl in particular, whom a year ago was a really close "friend" to me. Until I realized she's nothing but drama, and feeds off it. I've found myself lately, calling her out on everything she says, about anyone, when they're not around, and in general just not wanting to be around her. And in the past month she's quick to bring up how "confrentational" I am, when in reality, I'm just calling her out on stuff she's been doing for the past year in a half I've known her, it just never bothered me until lately.
So for me, yes, T definitely triggered more agression and anger inside me. But honestly, I think it was just stuff I was supressing before T, and now that I'm more comfortable within myself, it's coming out of me freely.
