I did the whole PUA thing for a while in SF. If you want to, going on 3 to 4 dates per week is doable, 2 per week is easy. Everyone is also very sex positive so getting laid regularly isn't hard either.

After a few months of that I wound up liking a girl enough for more than a first date. We were sort of living together within 3 months of meeting.

That last part happens fast in SF because rent is high and sharing rent helps.
