Is it right to have sex during mensuration......For married couples only

This is something that should be discussed with your lover as each person's sexual preferences and needs are different. If you're comfortable with the idea of having sex or messing around during your period, then ask your partner what his opinion is, or the next time you're on your period and he tries to make a move, just let him know and see how he responds. If he doesn't seem to care, you'll have your answer.
However, it's important to keep in mind that first and foremost, the option of having sex during your period has an awful lot to do with how you personally feel about it. Are you the type who experiences
mood swings or has to deal with horrible cramping? Are you normally withdrawn during this particular time of the month? These are all very legitimate reasons to avoid sex during your period.
Ironically, sex can potentially alleviate some of the discomfort that menstruation presents for a woman. Sex promotes blood flow which has the potential to minimize headaches and even relax cramping, and that's not saying anything about the obvious tension release! Thanks to endorphins released when you get down, sex can also be a great kick-start to feeling re-energized during a downswing of your mood. This can also be a time where the surge of hormones can create a heightened sense of libido, which can certainly benefit sexual activity.

Wrong! You can get pregnant anytime: Before your period, on your period, and after your period. Sperm can stay in the vagina for up to seven days, so even if you're shedding the last egg, the sperm might still be in there when you release the next one. So, unless you want to get pregnant — and maybe you do —i t's important to use protection or hormonal birth control.
Also, we should let you know that period-sex really isn't all that different than sex any other time. Sure it can be a little messier — and wetter — then usual, but sometimes that just adds to the kink! So, even if you're not sure that you're comfortable with sex during this time of the month, an attempt couldn't hurt. If it's not for you, then at least you know. But if it does work then you can enjoy a whole new experience going forward.

Now, if it's your guy who would rather avoid the dirty lovin' at this time of month, well, that's a whole other situation. For many guys, a woman's time of month is a turn off. This is mainly a mental reaction because physically things aren't all that different. If this is something you want to try, but your partner is hesitant because of the blood, why not turn off the lights? If all goes according to plan, once you two are turned on and ready to go, his focus will likely be on how things feel versus how they may look. If your partner prefers a little less clean up (not to mention the obvious protection from risk), you two can always choose to use a condom. Also, get yourself a large towel to spread over the bed sheets and off you go!  ........whats your own view?
