It is generally safe to watch sex videos during the first trimester of pregnancy, including the second month. However, it is important to prioritize your comfort and emotional well-being. If watching these videos makes you uncomfortable or anxious, it is best to avoid them. Additionally, ensure that you are in a secure and private environment while watching such content. Remember, every pregnancy is unique, so consult with your healthcare provider if you have any concerns or questions about sexual activity during pregnancy. They can provide personalized advice based on your specific circumstances.
