simple question.......

[Lap Counter]

SPEEDOS: I prefer traditional 2.5" side seam racing brief cut. Tyr or Speedo brand.
RUNNING SHORTS: I like em short, 1.5" to 2" inseam. Anything longer rubs my thighs wrong.
CASUAL SHORTS: just above the knee. I remember the short OP shorts of the 80s fondly, but never again.

SPEEDOS: don't wear anything longer than 2"
SHORTS: don't really wear them. Certainly not for walking around the streets, and for workouts I wear tracksuit bottoms.

1.5" sides are the best. It's the perfect amount of fabric on the side the serve it's function plus it grabs attention.
As far as the back, I prefer the Brazilian or a 3/4 cut on the butt.

Swim briefs: 1/2-1" sides with very low rise
Around town shorts: 4-5 1/2" inseam
Gym, in and around house shorts: 1" splits, 2-5" inseam (depends upon what I'm doing)
Evening & early morning shorts: 1-2" inseam

Swimming: 1 -2 inch sides.
Shorts, 5 - 7 inches since I don't wear underwear. Wore them shorter before I stopped wearing briefs under shorts.

For lap swimming I like 1.25 to 2 inch sides. Desmiit swim briefs is what I wear the most and they are 1.25 inch.

For walking I like these short shorts with a built in jockstrap. They are the most comfortable and cost well under 10$ so you can get many of different colors.

I really like the Speedo style briefs with made of polyester or nylon lycra with a 2 or 3 inch waist band, just below my belly button and wedgied in my rear buns showing the lower, half, almost like a thong style swim briefs. The kind , Iv'e worn over the years are like this style and well lined inside, not too tight and allowing breathing and space for one's genitals and possible erections from the gentle feel of the soft snug material. Wearing them when dry for a long time, they really feel comfortable and don't think about having them on. When these Speedo style swim briefs are wet after swimming, the wet clinging material does get me aroused, especially when taking them off. Taking them off really tickle all of my lowers, feeling the soft tight material slowly come off when first uncovering my now erect penis snug and secure in Speedo, then having to get almost off swimsuit unweggied from the rear, then finally peeling them down and off, bearing it all wet or dry. That's the kind of swim suit I really like wearing during the warm summer weather.
