My female straight friends flying in from LA and NYC feel like they Bay is a goldmine for women looking for ambitious partners, your "purchasing power" is a lot higher here.
At the same time, I don't think I've ever heard a single straight male praise the area for its love-life opportunities.
The peninsula and San Jose is terrible but the city and East Bay are good. Silicon valley is full of guts who have inflated egos because of their pay checks, but they have not much else going for them.
