I got an HTv4 standard. I hate to say that it's really too small. I liked the inconspicuousness of very small devices, but they don't worry with my anatomy. I thought the standard would be okay, but no. Girth and length are a problem. Here's my issue, I can order the largest size, but it looks really disproportionate to my (or anyone's) actual shape. The head is like be 3/4 of the whole length. An I missing something here? Is this actually the best for for someone a bit larger than the standard size?
