Our marriage is very strong, but we had some problems with sex. It because of everyday stress at work, and because of the ecology in the world and, sure, because of the age. So , I think, it's OK, if we use some medications, to save our relationships at the same level as before. I use Viagra pills, and, sometimes, my wife also, but special, female version. It works very well. We are both satisfied. And in your shop it costs accessible for the money.
