Here's my next question what type of panties r good to buy?

You have to look for something with full coverage, otherwise the junk will hang out.

Yeah I know but I have never bought them before soooo?

While shopping for boxer's for my bf at Kmart, I recall seeing Joe Boxer bikini brief uand thongs in the men's section. ...best of both worlds? Comfort of panties without social stigma attached perhaps for you? Might ease your S.O's apprehension

I like cocksocks they are pantylike but enhance the size of my package. When I wear them at the pool everyone seems to comment how great they are.

Im already wearing those was wanting more feminine ones, likely silky ones girly colors

I wear panties 24/7. I'm a big guy, so Just My Size (JMS) hi cut nylon panties are my go to. I'm not that big down there so I stay inside most of the time. Btw, if you're in chastity, go up a size and get some panty liners.

I like the boyshorts. They keep my boys tucked up nicely. Nothing worse than sitting on your nuts.
I especially like the 'barely there' brand. nice tight fit that feels like a pantyhose top.

Myself, I just get the JMS briefs. My hips are starting to widen some, but the bikini's still like to work down too easily and I find the briefs are comfortable and stay in place.

I do not own male underwear. I wear basic cotton bikini panties all the time. In pretty pastel colors of course.
Keeping my boy bits is important, especially when I am wearing tighter fitting women's jeans.

Here's my next question what type of panties r good to buy?

I have an eBay vendor I buy from that has good prices and is discreet. Right now it's satin or silk string bikinis for me!
