Question

In discussion between men,of various marital status, similarities were drawn in the psycological and physiological make ups, in a general sense. What do you think may be some of the similarities?

Answer 1

well the physiologically both are mamals and-so both s*x organs are similar.  Though, the dog's p***s has a bone (obviously the human p***s does not have a bone).

Both human and dogs are agressive...

Both are social and use s*x as a social tool...

to build social bonds and to define status.

Both are prone to having brief sexual encounters...
