My cousins want to go shopping?

Question

I am staying at my aunt's house with her and my cousins. My cousins are 20, 18, and 13 and are all male. I am 15. They want to go shopping for swimsuits with me because I am staying with them this summer. The only problem is, they wear speedos. I have three issues with this:

-I don't know if I am going to be buying one

-They might ask me if the suit fits and that would be uncomfortable

-I am kind of shy, with my body

Answer 1

I guess they wear briefs, Speedo is a brand. Don't be shy. If they are comfortable in briefs, you can be to.

Briefs are the only way to go. I am almost 50 and I wear them all the time.

Go for it.

Answer 2

Relax.  You don't have to buy one and if they ask you to, just share that you aren't comfortable with it.  I wear a speedo/brief to swim laps, hang out at my home pool and at the beach and find them to be the most comfortable and practical suit made for men.  This may also be a great opportunity for you to try one since you know they won't ridicule your decision.  

Consider the request an invitation to be part of their family and to include you in things.  I would encourage you to at least join them and go from there.  It may be a great experience for you!
