Well boobs are pretty obvious! Breast implants take at least a few months to settle, you need to support then with a good bra etc, you cannot lift your arms above shoulder height until the wounds are healed etc. Oh and getting a reputable surgeon to do breast implants on a bio-male may be a tad difficult.
HRT grown boobs are VERY sensitive at first, you definitely (in my opinion and experience) need a padded bra to protect them, protection as in you get them caught on everything from car doors to you name it, and they hurt when bumped to a point where you do stop and have to sit down and have a few deep breaths. You can't bind them. For example, I love being hugged by my BF but I have to be careful, I don't get them squashed because it damn well hurts!! He might think its funny but I sure don't!!
Cosmetically or hormonally altering your appearance is not to be taken lightly, it is basically for ever, so think about it. You may like the feel of having boobs but once you have them you can't take them off, and go back to being a flat chested guy in T-shirt again.
As for hormone driven changes remember that the changes can be dramatic and affect every part of your body and your brain/mind as well. You cant pick and choose which bit will change! I have nice boobs and nice skin, live full time as me and feel fantastic but I have no functional male bits (which is fine by me). What I'm saying is that you cant just flick a switch and change back and forward.
There are many very happy cross dressers who look great, have a fantastic and happy life and are very content with their dual presentation, but few want to make permanent changes. Permanent changes are just that! If you are undecided how to go, maybe book some sessions with a gender therapist to talk stuff over.
BTW there is nothing odd or unusual with your desires, you just need to be careful for your physical and mental health.
Hugs and welcome to the site!
