Does having a bent down penis make sex is different than guys who don't have that?

It shouldn't.: It should not as long as you point it in the right direction.

Can be different.: Depends upon size of penis ; degree of curvature. Penis with severe ventral chordee (downward bend) may be very difficult to insert and may slip out of vagina during intercourse. Bent penises are aften shorter ; narrower which can compound the problem. Sometimes sex with female partner sitting on top ; facing away is more satisfactory. Normal or longer length with mild curvature shouldn't be ok.
