Vagina tightness

I been feeling down lately, i was with my ex 2 years and sex just wasnt the greatest i probably honestly only had an oragasm with him about 4 times. I didnt want to hurt his feelings so i faked. Im not sure if its him or me, i am 20 years old, hes 29, i can grip my hand around his penis and have room left so he wasnt very thick nor in size about 4 inches but i never really could feel anything. Ive tried the finger test and i can actually fit 2 inside without a fight but 3 kinda hard to get in . Ive never been with big penis but i do have a wide set vagina im not sure if that is making my vagina feel bigger. I need some advice
