In my view the obsession of a large dick is misguided, my wife took a lover with a hugh dick, even i wondered how she was going to take all that.
It was exciting to watch and he lasted, but she said he was like a piston, no emotional contact at all and it was interesting but only OK.
The second meet became the last, she felt like a cow being bulled, no tactile touching, oral and little kissing just bang, bang and zero emotionally connection.
Now she wouldnt want a man with a micro dick, who would, but one of the best lover she had for years was an average size smaller than me, he would make her orgasm before he had even taken his undies off, the emotional connection was there, he was fantastic at oral and knew how to pleasure a female to completion.
He frequently changed tack with oral, passionate kissing, touch, mental seduction and BDSM and she loved it by the time he was ready to fuck her to conclusion many hours later she was so turned on it was incredible to see, listen or just know he was doing her alone.
She also took a young black lad as a lover and that exploded the myth that they have large dicks, he was in my words as fit as fuck but came with an average dick and little experience, We saw him twice but she didnt like taking the lead then getting little in return. We had hoped they would ...... together in our marital bed and have fun overnight but after a few hours of play he was done and tired so she slept with me.
Its says it all that the following morning we had both been up for a couple of hours as he lay upstairs asleep.
I know we are all different thankfully so i appreciate what floats your boat, but really it must be your wifes boat thats floated and excited, remember without her its a dead Duck.
I have found through these boards and chatting to real men that a lot have the desire to have their wives fucked by another male. However it often fails and doesnt work as the type of man they THINK she wants is actually wrong.
