I dunno how is to b small but i have a very good friend of mine who is "pretty small" , he has no complex at all , he's good looking and everything goes great in his sex life , very true .So to answer ur question , act as usualy u do , and as u said u would.Size is related with the psihic at men .If the men is a strong personality and handsome , small dick wont affect him i can tell u coz i saw few close cases.So what u can do is to help him psihicaly if he seem to need it.
oh man well ... dont laugh at him that is for sure.. ha ha....
you should just smile and pretend it is cute...
but if he cant use is tounge then laugh........ say get the fuck out.
