Neptio Athletic Mesh Thong for Men

I like the looks of the Neptio Athletic mesh thong and Iv'e a couple questions before purchasing; Is the pouch stretchy? I measure between a 35 - 36 more or less, ;am thickly endowed with loose nuts. I'm also UNCUT with a very sensitive cock head. is the pouch sheer and stretchy? I want something stretchy so I don't constantly have to readjust 'the guys' Also since each designer - manufacturer cuts their patterns differently I've found measurements and sizes can vary, especially with things and g strings. What size do you recommend so i don't buy the wrong size and waste my money? Hope to hear back soon as I'd like to take advantage of your 25% off sale. Thanks

The fabric is stretchy, see the description for the size chart which is based on fit.
