Yeah it's 100% men do it. I had joined yoga course few years ago and during "yoga and sex" topic he asked those men to raise their hands who had never done it. We were about 60 students including women. When not a single guy raised his hand, women saw at us surprisingly as if they never did it in their lifetime.
I believe women too do it but I won't say it is 100%. Most of the women dont admit to have done it.
