Help with a steering problem

I have a 95 Civic and I'm sad to say that I don't know much about it mechanically. My problem is while I'm driving the steering wheel slips when I turn. For example after I make a right turn the top of the steering wheel will be on the right side, after I turn again the top of the steering wheel will be where the bottom should be. Does anyone know how much this will cost for me to fix?

So after you complete the turn (i.e. turn right and then go straight) the top of your steering wheel is pointing to the right and the front wheels are going straight?

Is it the factory steering wheel or is it aftermarket?

Yes that's correct, it will end up going around in a complete circle. It is factory.

do you have SRS ( airbag ) ?

Yes I do.
