Well, being a top or a bottom has nothing to do with male or female, so keep that in mind.
Also, being very feminine does not make you a woman any more than being very masculine makes you a man.
The way we get this way implies a lot of variation so you just have to figure out what works uniquely for you, there isn't a set program. If you don't feel genital dysphoria--great! Dysphoria over your genitals sucks! And plenty of trans women never go in for SRS, dysphoric or otherwise. Be aware, though, that your genitals will change on HRT. You are also going to start growing breasts. If you're okay with that, great. But you can't pick and choose your changes.
ETA: your sexual response will change on HRT. It will move away from being so focused on your phallus and start to encompass more of your body. Because of this, on HRT you may find that these sexual fantasies or obsessions that trouble you so much go away on their own.
