Sometimes it takes a few months to get pregnant, regardless of how willing and active the participants are. This is not a sign of an illness or a problem -- it's just the odds at work. I'd say, though, if you go for six months of sexual activity, with no birth control and the man achieving orgasm pretty much every time if not every time, and you're still not pregnant, contact your doctor and ask.
And, by the way, even if the man achieves orgasm, the problem could be on his end, e. g. low sperm count, so I'd have your partner get checked then as well.
Your age, traditions, daughter, religion and family have nothing to do with this -- this is biology.
