dating is a weird beast.
From what I've seen on the domains I have parked in the past, they're something between an 'adult' domain and a 'normal' domain.
They can bring great revenue if traffic comes from countries with high CPC.
Now, asian traffic (by asian what do you mean exactly?) doesn't bring much revenue per visit but I believe it's worth a shot parking them (I'd try ParkingCrew first) just to see how they'll respond.
If you'd like you can pm me while you park them and I'll share with you what I've done with my own dating domains. Maybe that will help you set them up in the most profitable way
