I saw a tv show about porn and the affect it has on teenagers eg boys getting the impression that ejaculating into a girls face was their right and generally getting a tainted view of what they can expect from a sexual partner. But perhaps as an adult who has experienced the reality of sex ( take your partners feelings into consideration as well as having to please them while also trying to get yourself satisfied ) you are finding pornography more stimulating because it's about you, none of that considering someone else a sense of being able to do exactly what you want, to be selfish without the consequences, just plain self gratification which leaves you able to get an erection without meds. If that is the case perhaps after conversation with your wife you could re-enact something from a porno or role-play your filming your own. Have fun with it ��
