Why do i always feel like i need to vomit after sex?

Physiologic: Different people have different reactions to sex. Some women cry after sex, others have an urge to smoke. Vomiting is your normal reaction. Do not try to obsess about it. It is likely to abate as you grow older. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.
