Thank you for the kind reply. I looked at the links you guys posted for me. Terry has a lot of interesting stuff but since I'm a beginner I don't want to start buying everything without even knowing better first.

and MangoPumpkin, Thank you for the explanation. I checked the picture but it looks very similar to what I have now. My husband just bought me this columbus bike from sports authority and it is a woman's bike so it has woman's saddle attached already. this is the picture of it.




It is softer than my husband's bike on the butt and also on the tip.. I guess that part is called nose??
And the nose is what hurts me and gives me pressure.
I did some research and I think my hands were numb because I tilted my seat to reduce the pressure but that made my body weight on my hands. At least that's my guess.
My husband says I am holding on too tight since I just learned though.

Unfortunately I can't change positions nor take my hands off one at a time without falling. I'm not that good at keeping my balance yet. Everytime when I was sliding forward because of the tilted seat, I couldn't just move back a little so I had to stop and seat back and start riding again.
Hopefully I can be good enough to ride on the road soon.
