At what time/part of a monk's training is he free from sexual desire?

I know this can be subjective to each individual, so I am only looking for a general idea rather than a definitive answer. Is it once one is at anagami stage? Or does the gross desire leave before, at certain stages of practice? Like jhana stages as an example? I remember Yutadhammo specifically stating in a video that the desire for sex is actually a relatively easy desire to be free from. Gross desire and more stronger, ingrained desires are much harder to rid oneself of. Though I expect that was also a individual experience.
