There are two key benefits that using breast pumps can bring for both your sex life and your personal life. The first is the benefit of an enlarged breast, that look perkier and sexier. Depending on what you and your partner are into this should make sex session a much more steamy affair. The beauty of it is that this is temporary so if you think you've gone too big you can always go back! The second is the increase in sensitivity especially around the nipple area.
