Well, yeah, i agree. It depends on what you are feeling at a time you have sex, if you are not feeling well enough, and still you forced yourself to have sex, then sex could not make you healthy, I guess, it can make your condition worst.

Have sex, when you feel like it..don't have it when you feel you don't! But makes sure, when you have sex, it's the right person you are with and of course, you have to do safe sex!

Yes, I agree that it depends upon the situation about the individual. If the individual is not feeling well and he/she force himself/herself to do it, this might get bad result to the body. But there are some who becomes healthy and strong when they make sex even if the are not feeling well.

this can alleviate your feeling if you reach satisfaction, but it is done with consent to the partner. this is done with love and care, not in experimental ways.
