Women also enjoy when a man ejaculates during orgasm, his, hers or both simultaneously. It makes them feel like they caused you satisfaction and that they have what it takes to get you off. A man feels the same way when he causes her to orgasm. When it gets more difficult for a guy to orgasm, some women will blame themselves, not knowing that his "load" may be decreasing as he gets older. Many of us will deny this until we get medical proof. Men still enjoy sex even when we don't blow our load. Our primary worry is losing an erection during sex. Viagra and its counterparts, Cialis, etc, do nothing for semen or ejaculate volume. They just keep your "dick" from going limp too soon. Personally, Viagra causes me headaches after I have used it and go to sleep. I wake up with a headache all of the time. I know it has to do with the fact that it increases blood pressure. I'm thinking about not using it anymore, but I am at that time of life where I lose my erection at the most inopportune time. Viagra has helped for that purpose, but I'm wondering if the trade off is worth it!
