Thanks for query,
I appreciate your discomfort & solution for it.but you should remember that sex is in mind & not in organ.
operation was done.In this operation they cut your fore skin but not vessel supplying it & then ligate it so that it continue to supply your penis.
Penile blood supply is important for arousal.When you have more blood in it you start arousal reflex & erection.
If you go for re operation to correct it it may shorten more makes you more discomfort.
So leave all thoughts about its curvature or rotation & leave all worries while enjoying sex & just divert your attention from it during sex gives you more pleasure & no discomfort.
