The answer is a bit more intricate than one would think. To keep it simple I will break it down into two parts:

For men, yes
For women, no

According to medical research, frequent sex promotes firmer thighs, tummies, and buttocks in women. Regular sex can even improve a woman’s posture. However, men can have too much sex resulting in damage to the male reproductive organs. While the penis is flexible, it does have limitations. Too much pounding and roughness can cause damage to penile tissue. When the damage is severe it can lead to permanent damage. With the advent of male enhancement drugs, and ED pills like Viagra and Levitra men can go longer and push their bodies harder. This may or may not be a good thing.
