You really have to take your time (as much as you need) and make this decision for yourself and for the right reasons. No one else can really feel what you feel, know what makes you happy, sad, mad, etc. Transitioning is to a large degree a self-diagnosing process. A good gender therapist will also be invaluable to you in this process. If you don't have one, get one asap.
I myself knew something was up since around 4-5 years old. It wasn't until I was in to my teens and finally learned about other people being trans, HRT, SRS, and all the fun stuff. Then everything sort of started to fall in to place for me and I was able to better figure out WTF was going on. Take your time. There is no bonus score for racing thru everything. Transitioning is long, hard, and expensive process. Definitely a measure twice, cut once procedure.
There are a lot of great surgeons out there. I'm in the USA, so if you search around you will find many recommendations as to who went to whom and why. SRS prices in the US range from around $20,000 - $30,000 as a ballpark average. There are some surgeons who charge much less or much more outside of this range, and that should be a red flag from the start as to why. You also want to research each doc's aftercare, methods, and follow-up procedures. Aftercare, dilation, recuperation, is a huge, not much talked about part of SRS. SRS is just the beginning of a rocky road... you have to keep this new organ in tip-top shape, which requires a good deal of time and dedication.
I also have had many boyfriends prior to my SRS, and now today I'm with the same guy afterward my SRS. He didn't care about what was between my legs either. He was just as happy with me either way. I had my SRS for me, for my own reasons, and to be happy with myself. Not for anyone else or to make anyone else happy. You have to do it for yourself.
Good luck.
