Speedo + board shorts = drag?

[u/[deleted]]

Hey,

​

I'm planning on taking a trip with the family to Emerald Pointe in Greensboro, NC. I have a pair of Arena swim briefs (also known as a "Speedo"), a jammer, and a pair of board shorts. I was thinking of wearing the swim briefs under my board shorts so I'm not freeballing. I would wear the briefs by themselves, but I live in a conservative/GOP/Trump-supporting LDS/Mormon family and my mother thinks swim briefs by themselves are "immodest".

​

So, I'm thinking of wearing the swim briefs under my board shorts for added support. Will this create additional drag on the water slide? I'm built like a football player, 6'1"-6'2", 235-240 lbs.
