Answer

Is this a

DATE?

My first teapot is sticky sweet

Date, the sticky sweet fruit.

My second's not all the time

Only certain dates of the year are sticky or sweet as well. Could this refer to the fact that only certain dates were on Madonna’s Sticky & Sweet tour? One date occurs every 365 days or so, it doesn’t occur all the time?

My first teapot likes it hot,

Dates grow in tropical conditions.

My second doesn't care about climate

Dates on the calendar occur no matter the climate.

My third teapot is hopefully sweet too,
But you'll never know before you try

This references going on a date - hopefully your date is sweet, but you won’t know before you go on it!
