Yes, you can have sex on your period. Sex during your period can be very fulfilling and, owing to the change in the balance of hormones, you may even experience new sensations. Of course, the presence of menstrual blood might be something you or your partner may not feel comfortable with, in which case, you could try anal or oral play instead.
It’s also worth bearing in mind that, while pregnancy may be less likely in the earlier days of your period, the chances of becoming pregnant do gradually increase as your period progresses. If you are planning on having sex during your period, just remember, safety is just as important as it would be at any other time during the month. Not only can you still get pregnant, but you are also still at risk from sexually transmitted infections (STIs), so it’s important to use a condom.
