A: Your semen will be sweeter if you eat more raw vegetables and fruit. If you're a heavy meat eater, you might consider shifting your diet. Sometimes the medications we take can affect flavor. Drugs taken for depression and ADD contribute to strong, bitter tastes in semen. Stress may also be a candidate. Take note at the times it seems sweeter and pay attention to what you might have done differently. Don't give up oral sex because of this. One intimate thing to do is to share the semen through a passionate kiss with each other. That way the volume stays lower for her and you both can keep better tabs on dietary changes that might help.
