-twoway rcap- here draws the bars. To do what 
you want you need to add other graph elements. 

Alternatively, as a canned solution, 
-serrbar- will get you most of the way. 

serrbar mean se x, scale(2) 

Connecting only for the same country and sex
complicates matters, however. 

Something like this should help. 

preserve 
bysort country sex : gen last = _n == _N 
expand 2 if last
bysort country sex : replace mean = . if _n == _N 
by country sex : replace x = . if _n == _N 
serrbar m se x, mvopts(c(l) cmissing(no)) 
restore
