Another transguy feels *too* interested in controlling my own transition

For bit of context, I am a 21 y/o transguy currently in university. I'm just over a year on T and haven't had top surgery yet (hoping for next June 🤞)

I work with another transguy who's a lot farther in his transition then I am. He's 8 years on hormones, 7 years post top surgery, and a few years post hysterectomy I believe.

It's nice being able to talk to someone else about trans stuff, since I don't know a lot of other trans mascs. But it feels like whenever we talk transition, it feels like he's trying to push how he transitioned on me and change the way I'm doing it if that makes sense? I use T-gel, since needles kinda freak me out. I can handle doing blood donations every few months but I really don't like the idea of having to do shots once a week. It feels like he's trying to get me to switch to shots, despite having no interest. He's said he can talk to someone about getting me in as soon as possible even though I didn't ask. Earlier today he asked again why I don't want to switch to shots, if somethings putting me off. I feel a lot more comfortable doing gel, and since I do it every night it feels more routine to me. I don't feel like there's a need to explain why I prefer doing it one way or another.

Another thing that bothers me is talking about top surgery. I have double Ds and will need to have double incision and liposuction. The liposuction isn't covered by OHIP in Canada, despite the surgery itself being covered, but I personally think my outcome would be better if I get lipo while under. He was able to have keyhole done since he had a smaller chest, and when talking about my future top surgery went 'but you'll have noticeable scars'. First off, I don't have a choice. I can sure try to have keyhole, but my chest is too large to even consider. And secondly, I've always thought the scars looked super cool, so I don't see the problem in having them. It also feels like he's trying to get me to get it done as soon as I can, but along with the liposuction fee, I also need to have money set aside for rent and can't jump the gun without being prepared. I also have to have it done during the summer, since I'm a music student in university and will be out for at LEAST a month before playing again, especially since I play the trombone. There's a lot for me to consider before being able to have top surgery, but it feels like he constantly forgets that there are other things to worry about.

Other things I feel like I should mention is when talking about transwomen, he claims that they'll 'never be real women' since they can't give birth. He can't GET people pregnant, but that doesn't make him any less of a man. And plenty of cis women can't give birth either. Also everytime we talk sexuality (I'm aroace), it feels like he doesn't believe aromanticism exists? I've known since I was 16, but he always seems to push that 'I have to wait for the right person' and that it will change. It MIGHT, but that's for me to explore and not for him to argue

Is there a way to go about making him mind his own business about I choose to transition without being a total dick? I do enjoy working with him but the pushing it feels like he's doing is driving me up the wall
