A harmonious sex life is an essential step in maintaining a couple's relationship; in fact, the quality of intimacy directly impacts the relationship. Diet also affects the quality of sex life, and the following two types of food are not suitable to eat before or after intimacy.
Avoid eating greasy food before sex.
In daily life, many couples enjoy eating greasy food. While greasy food is certainly delicious, consuming too much before sex can easily affect a man's erectile function. Experts say that a man's erection during sex requires the use of various hormones in the blood and muscles. Among them, testosterone is a very important sexual stimulant that can arouse male libido and help achieve an erection.

Eating a greasy, unhealthy meal can significantly suppress testosterone production. This is especially true of formal Western meals with five main courses, which are extremely high in oil and are a silent killer for sex.
Therefore, eating more carbohydrates before sex can quickly replenish energy and prolong erection. If you want to eat before sex, consider pasta, toast, or potato soup. Those who prefer meat can try replacing beef and pork with moderate amounts of animal liver, fish, or shellfish. However, it's important to note that it's best to eat an hour before sex, otherwise you may experience dizziness and nausea during intercourse.
Don't eat cold food after sex.

During sexual intercourse, the sympathetic nervous system is more active, resulting in reduced blood flow to the gastrointestinal tract compared to normal. Therefore, drinking ice water immediately afterward, before the gastrointestinal mucosa has returned to normal blood flow, can cause sudden cold exposure and damage to the gastrointestinal tract. In severe cases, it may even lead to gastrointestinal discomfort or cramps.
Therefore, experts suggest that if you feel thirsty after sexual activity, you can drink a small amount of warm or cool boiled water, and try not to drink ice water or iced beverages.
