Dear kamran nothing to worry as you have been with your wife for 2 months only for any couple it is thought that as they get strated the married life immediately wife shud get pregnant.we give at least the husband and wife to have sex regularly for one year and it doesnt result in pregnancy
then to think over it,be relaxed. dont doubt about yourself. early discharge is common in newly marrieds it gets settled as you understand each other sexually . finally any healthy man can repeat the sex after first in younger age its matter of minutes as age advances the next session of sex takes longer time to get strated varies frm individual to individual.
