Not every girl wants or needs SRS. Lots of transgirls are perfectly happy with their parts as is; and also, that's normal of you to feel undecided... In fact, it's probably better that way.. Better to have time to think about it instead of desperately wanting it gone. Pre and early transition, I was hell bent on never getting SRS for 2 reasons:
1- I felt not opting for SRS would somehow make me exotic
2- the idea seemed crazy to me.
Fast forward to 2 months on hrt... And I'm beginning to consider it because the idea starts to intrigue me, but still a hesitant idea.
Fast forward to now - I'm about 80% sure I want SRS, not because I hate my genitals, but just because it would be nice to feel "correct" (IMO, that's not to say that choosing otherwise is incorrect, just the my personal opinion of correctness for my own self image, would include SRS) the only reason I'm currently 20% unsure still, is because of money, surgery risk, if I'll have the availability to go through the long recovery (job, life, etc), my wifes feelings about it are still somewhat unsure, and also just trying to get comfortable with the idea of no longer having something I've had for all of my life and using it to do the things I do now, the idea is intriguing but still gives me chills. Also; I have a phobia of surgery, so id need to get over that... While that sounds like a lot for only 20%... The other 80% of me sees my current equipment as a total detriment of my own self image, when I "hide" it and make myself look proportionately correct, it takes away my dislike for VARIOUS parts of my body, almost like magic. My dislike of my legs or stomach or waist, goes away simply by hiding that one part.
So yeah, it's up to you and only you, to make that decision, and it doesn't invalidate anything nor cause problems. Though your opinion might still change in the future as mine has.
