Several posibilities: Among other issues, your partner may not have prepared you properly prior to intercourse, you may not particularly appreciated your partner as a sexual entity, you may have psychological issues about sex, you may need changes in position or alternative techniques by your partner. Some women are more able to have orgasm with oral stimulation. A sex therapist may help.
