How long after HRT can I expect to stop having erections?

Can you answer Chelly’s question about Menopause?:

Erections are so annoying(and weird) for me and I know after HRT they’ll stop, but how long after?

and can I expect to start getting female like erections in my nipples when I get “aroused”?

Sorry for the weird question but I would appreciate serious answers from Transsexual or Transgendered Women who’ve experienced this.

(To clarify, i’m a Transgendered girl/woman)
