compression shorts?

[MTnoodle]

Should I get some to wear under my Muay Thai shorts? I haven't gotten my shorts yet but I am required to within the first three weeks. The only shorts I have are long and come past my knees (my basketball shorts) and I think they kind of inhibit my kicks. Do I get compression shorts based on my shorts size or do they wear smaller or larger?

thanks,
Mike

if you're sparring, then yeah. i think they hold my cup in a lot better than an athletic supporter. but that's just my opinion.
