I've used this several times now for solo and partnered sex, and it has not disappointed! I'm pre-T but even so with using the NYTC pump was able to get some suction (enough to be "hands-free" so long as we didn't tug too hard) along with a very healthy dose of euphoria! I'm a bigger person, and it seems a bit small/awkward as a packer to me, but it's super soft and comfortable. Thank you NYTC!
It has a great size and softness that makes it extremely comfortable for packing - small enough it doesn't make a huge bulge, soft enough it doesn't feel like a boner. I usually use a packing strap with it so it doesn't shift around.
For masturbation, it's a little trickier. For the record, after bottom growth on T my dick is around 1-1.5" long. It's hard to get much of my dick inside because the opening is very narrow, and as I use it it tends to fall off over time. Maybe my labia are blocking it too much? The ridges inside are a little sharp and sometimes too intense, even with lube. I enjoy using it, but it takes some effort to get it situated correctly.
On the occasions where I successfully attached it firmly, it was really cool because I could just leave it there and, essentially, pack while naked. The color isn't a good enough match for it to look completely right, but it feels good.
