The vagina and rectum are only separated by a thin membrane. It is not uncommon for some women to have this sensation. I would ask do you have constipation? This may mean your "lower" bowels are not completely empty. Also, some women have hemorriods which also causes more pressure in that area. What we often suggest to clients that you try a different position. Female on top or side lying positions help. If your partner is on top it adds extra pressure on the digestive system and the bladder thus causes the feeling. The reason it seems to get worse during an orgasm is because your muscles are contracting. Yes, some of the muscles that are used during bowel movements. This is why some women will poop when having a baby not to mention the pressure on that area. Try to relax. If you are just going into sex without adequate foreplay and relaxation your are tensing up. That will make it more likely. Get online and research more, plus you also need to learn more about your own body. The more you know the better sex will be so find a good book and begin reading. I hope this helps...

i agree

I am more submissive -( but i think it also depends on who you are with )
generally,all woman are made submissive,first they take time to decide whether to get his seed or not,once they like,they simply surrender and open their legs,inviting to make them pregnant.only just for variety or when not satisfy by male,they take act in theit hand,and get self satisfaction.

yes

I had relations with half of my age, married woman,(more than five,all very young and married to all most same age guy},they will specially visit me for sex,as they get more satisfaction from me.I do not know myself as old man how I am better than their young hubbies.but its hard fact,that in my office many young married girl meets me once in a week.
