Hi I am 30 yr male with weatish color, my skin color is darker than my natural color at my buttock's & inner thighs,& I am getting married this month I feel little bit shy to show my private area to my partner... *** advise how to remove this dark skin color & need to improve my butt bigger...

All I can think of right now. Is... a spray tan. Or tanning. Or visit a gmc store they might have something over the counter to help with skin care. Also purchase a loofa spongue and some good organic exfoliting body scrub.
Best of luck to you
