Between friends, there are often times when gestures are much louder than words! For many, the "touch and feel" is much more indicative of what is important than any verbal communication is able to provide!
This is true for both of the men here today. Their individual preference for sexual gratification is obvious for those of us viewing the scenes above! One prefers to penetrate rather than deliver and the other would rather be the recipient of the physical expression!
Both ways of expressing themselves are acceptable, although, from personal experience, I find the involving of both in the act of communication gets the message across in the best manner possible!
Peace!
