why doesn't penetration feel good?

ive heard from many women that penetration is heavenly but ive only been able to stick in a finger. when i use a fingers in doesnt really feel good just wierd and after moving it around it starts to feel uncomfortable. i cant add another finger without pain. i make sure i move slow and that im aroused but nothing seems to change. im still a virgin and im a little bummed out. if i cant even put in 2 fingers how am i supposed to take a penis? i would prefer not to do clitoral stimulation my whole life.
