I fully agree that this is a 2-way-street. But in my experience over the last 27 years of relationships, women still somehow think that simply responding to male sexual drive is enough, while most young men nowadays are keenly aware about the fact that permanently lusting over their partners is a very pushy thing to do, and they have adapted to that reality. Also, young men (at least the ones worth of being in a relationship) also realize that this is a 2-way-street. So it is only fair to expect from this lady - who is publicly complaining instead of talking to her partner, which in itself is somewhat fucked up - to voice her desires instead of holding her partner to an impossible standard.

Edit: she can complain publicly again if her partner categorically refuses sex with her regardless of circumstances, but she might be better of separating at that point instead of whining - there are enough men out there that are viable partners and who would do a lot for that opportunity - if she is a decent partner herself.
