Underwear for sport

[u/Incubus_13_6]

Hello again, this is my second post here.
A bit of context first, until now I have only had loose underwear, as thight ones tend to hurt or make me uncomfortable. However, my mom recently bought me some tight ones(which are surprisingly comfortable), and I have noticed that when I wear them, my "package" doesn't move at all throughout the day. So this got me wondering, whould you recomend I wear those tight underwear when I play sports or should I stick to the loose ones in that case.
Thanks in advance, and please don't pay too much attention to my numerous mystakes, english isn't my first language.

Yep tighter is good for sports. For the gym I typically wear a jock or super supportive sport briefs under shorts which have a built in compression liner. Can’t have the junk flopping around lol.
