go for practicing it then. just realize its an extremely difficult thing to pull off and there's a good chance you will fail. you'll likely have to either accept your masculine voice or an obviously trans sounding voice. im sure youre doing it already but try to google up whatever voice training shit you can find, i have no clue where youd look, though.
another thing to keep in mind is most women, trans or cis alike, dont have sultry voices. and, there's plenty of cis women who dont even sound particular feminine, so its not like the problem is unique to you or even trans folk.
