I find myself constantly worrying about pregnancy even tho i haven't been active for 3 months. why am i having so much anxiety about sex in general?

Sexual anxiety: Sex/pregnancy is a big change in life/ relations/responsibility. Concern is not unwarranted. Seek psychological counseling as well as discuss birth control options with your doctor. Proper evaluation/reasoning/preventive measures is a sign of maturity and adulthood. Ask your doctor or go to the American Psychological Association website (under psy help) for referral.

The way of DNA: This may be a symptom of psychiatric distress, you may want to have a counseling session evaluation. However it may be entirely normal to feel sexual pressures. Our DNA has programmed us to reproduce and once that happens and our children are raised, it doesn't keep its vehicle [us] around much longer. If you are depressed, anxious, or insecure these drive may be accentuated or reduced. Seek help
