Good or bad surprise?
 

Sorry I've been gone for awhile. I want to start posting again!
Anyways, I went running at night in these shorts tonight. Turns out, they're a little bit see through after sweating. Good things it was at night. What do you think?

For something worn when out running at night, it's way too revealing.

Try something that's completely opaque and looser fitting like conventional short running shorts. Also wear underwear that completely covers your junk.

Sorry for my disappointing advice, but I don't want you get a trip to jail for exhibitionism/indecent exposure!!! :p

Good advice! I came home late tonight and I wasn't really thinking. I normally run in regular running shorts.

Good to have you back on the board.
You have a great body, looking young, fit and healthy, but perhaps the general public are not ready to see you like that running the streets.
On a quiet beach where few people and even fewer women and children will see you they may be suitable but I'd prefer to wear something briefer maybe speedos or a bikini (possible even something sheer and light coloured).
If you have a woodland trail where few people go it might be fun to wear them there. Try not to cause offence to the extent that someone calls the police, though there is a quiet footpath beside and over the M1 motorway in England where a naked runner is often seen and reported but has not yet been captured.
What are those shorts, are they intended as underwear?

I'm not too sure. I'm normally not the type of person that likes stuff like this. I came home from a stressful day and just wore the first thing I can grab out of my closet. Then I came back home after my run and discovered that it was see through. I was just embarrassed. I thought it was funny to share.

I think we all have had an experience of wearing something and not realizing the item was virtually transparent. It's good you found out when it was dark and there were no kids out. You got some good advice here and it sounds like you aren't out to be a one man peep show. That said -- i'd love to have you as a jogging buddy in those shorts!
Welcome back

Welcome back. I had a similar situation earlier when I noticed my cream colored shorts were see through from sweat. Now I don't wear light colored shorts without something underneath them.
