I bought it for my husband to increase his stamina and frequency for intercourse. Since he started hitting the road more he gets out of practice. Never had that problem in his 20's but now in our 30s, we all need work to stay in shape. He was never an avid masturbator like me so I felt the convenience and pleasure of it would get him masturbating and exercising that beautiful big cock while he's away. I tried it on him several times he came very hard each time - he loves it.
He put it in the glove box and promised to use it whenever the urge arose (though not while driving). It was so convenient to get to, use, and cleanup, he found himself using it more often on each trip. He's really into masturbating now (not while driving, usually"). Now, when he returns home it's like he never missed a beat and our sex it great. His cock seems more wanting and harder for me than before. We have as much sex as before but when we're not having sex I like to use it on him and watch his face while he ejaculates- the pleasure is so much more intense for him now.
