Cock size alone will not seduce a lady. She needs to feel special and any potential bull needs to know what her individual buttons are so he can push them in the right way.
Those bulls that say doesn't matter what she wants .....she is getting it anyway, probably don't form very long lasting relationships.
The husband will know what his wife likes and dislikes and be a good source of information for a successful bull.....so listen to him guys.
I am often asked does she take it up the ass! When I tell them she does not even contemplate the idea they tell me.....she will with me.... Like she will have fairy dust sprinkled all over her.
Once a bull has got to know the wife's likes and dislikes he may well get her to try hitherto untried things. Or even revisit experiences that she did not like first time around.
The key to success is for him to build trust. Put the lady first and listen to the husband.
