What aren't condom designs improving?
Doctors are always worried about the amount of people having unprotected sex BUT comdoms' do destroy 98% of the feeling making them unattractive. Equally, for some people it makes the experience unpleasant and even painful.
Therefore such people opt for gulping it down or all over the face to avoid pregnancy. I make my reference only to heterosexual people. Since this is a serious off putting issue why is there no research to improvement in this area?
