How long should sex hurt after you lose your virginity?

for me it hurt the six first times, so that was the first 1-2 months.

It should last only a very short time. It is important for the first few times for the woman to relax and not tense up. It hurt for the first few times until I realized I was tensing up my vaginal muscles without knowing. Once I started relaxing and releasing the muscles, I really started enjoying sex.
