For my birthday, the girl that I swing with got me a few pairs of underwear along the lines of these: https://www.hugoboss.com/us/stretch-cotton-trunks-3-pack-brief-3p-co/el/hbna50325403_487.html?cgid=24003

She suggested that she take a picture of me wearing them while hard and post it alongside the picture of her in a bikini that exists in our personal ads. Her breasts are prodigious, and while she loves the attention that her scantily clad pictures bring, she wants to show off what I'm packing in hopes of finding other couples with hung men and women who are into that kind of thing.

While I like the idea of showing off, I'm a bit worried about how this will be received. Does this seem like a good idea? I'd love to hear some opinions before diving in.

Thanks.
