Is it normal that I don't have a orgasim during penitration?

Yes, true for many. Penetration & vaginal sex alone does not mean that orgasm can necessarily be achieved. Stimulation of the clitoris is more likely to result in orgasm for many if not the majority of women, and is more sensitive for most than the g spot. Digital or oral stimulation of clitoris before, during or after vaginal penetration may be required for you to experience orgasm. Good luck.
Yes. Everyone's orgasms are different, and may require more or less stimulation.
