I think at the end of the day, you have seen all the sex you want and now you need the real thing, a good women and some real sex, you will be so surprised at what will happen then.
Nothing like the real thing with a good women, hands up who say yes to that.
Good Luck
You don't get erections because your mind/eyes are use to seeing porn.
Some times, you may get acclimatized to poron and hold no attraction for the same. In one way it good that you are not addicted to porno. If you are addicted to porno, it is likely that you will have ED problem while doing a natural intercourse.
