The level of fuel in the tank cannot affect whether fuel gets into the oil. As Steve suggests, if there is fuel in the oil, you have a fuel delivery problem, and a bad one. This can only happen if so much fuel is being dumped into the cylinders that it is getting past the rings and into the oil. This was much more common in the past with carbureted engines, but I believe that your motorcycle is fuel injected. I would doublecheck that it is fuel in the oil. If it is as bad as you say, you should be able to smell the fuel in the oil.

This is OK. Oil pressure is always higher when the engine is cold.

As an engine accumulates miles the pressure will start to drop due to bearing clearances increasing.

If this just started to happen you may want to replace the oil filter and or oil pressure sending unit.

Testimonial: "Many Thanks, geat help I will do this."

My 2009 glamour bike gives low mileage-45-50kmpl.white smoke used to come in between but has stopped now. engine oil levels drops every 1000kms. engine tends to get off in between while driving. no pickup....

You may have contaminated fuel i.e. water in the tank mixing with fuel causing poor performance and excessive white smoke. If it is a carburettor bike the carb may need a service... Oil does drop slightly on some bikes but it depends how much its dropping by. If its like half a litre or more you may have trouble ahead. Get it looked at!!
