Those secretions come from various uretral glands which aren't to be removed, no matter what your
surgeon and what the technique. The amount of them will mostly depend on your hormone levels
(even with the Testis removed, your body will produce some androgens the same, mostly the adrenal
glands). Those are the same androgens responsible of sex drive even in females. You may end up having
them very low after some months, so no secretions, or still have some. It will depends on your body and on
your HRT. The only issue is that, being them urethral secretions, they're not always so useful to lubricate the
vagina for an intercourse, unless they're very copious and/or the urethra very close to introitus. Here is
where the surgery technique might make some difference. Btw, never forget about female eiaculation, it's
pretty the same thing.
