You don't need it no, you look great. If you want ffs though, then do it, just keep it subtle and stick to your guns.
People told me I didn't need ffs, my parents spent a good while trying to talk me out of it, but I went ahead (eventually with their full support). I don't regret it for a second. Hormones were never going to change my nose and chin to any great extent. Whilst I often passed ok beforehand, I still sometimes got those funny looks... It depended on the lighting I think! FFS just removed those little tells.
I'm not dead against surgery as long as it's been thought through and with the right surgeon the results can be very natural. Actually in your case the results would definitely be natural because you would only need subtle changes.
By all means wait though, you don't lose anything by being patient 😊
