What I Have Tried Thus Far
I first tried just men's bikini briefs as they were comfortable with extra room before I wanted to start tucking... Then, especially once I got into leggings, I decided I both needed to tuck but also wanted to have cuter panties. So what options have I tried?
- "Boy Shorts" (Honestly don't like these that much, they felt like they had too much material on the sides and back while not enough on the front)
- Bikini Style (Women's) Panties(I Love these, they are comfy, and I can tuck with just them... for a couple of minutes, and then it is bulge time again. At least it is with me and the ones I have tried) Microfiber Cotton
- Control Panties/Shapewear (The ones I have tried will keep everything thing smooth down there all day no problem, just wear regular panties underneath them. I will say, though, they are all fairly tall, and I have to readjust the waist throughout the day. Plus, they don't look that cute, and they can sometimes compress your butt a little bit.)
- Tucking Gaff Thong (slim, typically wear underneath a cute bikini pantie to avoid having a "thong line" visible through leggings or skinny jeans. Downsides are it is sometimes a little harder to tuck without spillage, and it can be somewhat uncomfortable if it starts to ride or move throughout the day. Aside from that it is one of my favorites as unlike the control panties it can go under my cute panties, and they don't compress the butt like the control panties do to some degree and let's face it, if you are wearing leggings or skinny jeans your butt is important.)
What I refuse to try
I don't want to use the tucking tape or the specialty tucking tape adjacent products. I want something I can comfortably do while at my job and I can re-tuck with easily at work. Plus, I don't want to spend money on a disposable solution... I may try one of the swim safe ones like unlockables when I someday work up the courage to go swimming, but not for every day.
I wear very small bikini style panties much of the time and I have no problem keeping my tuck in place. However, I'm not very large down there so that might be a contributing factor, so YMMV. As long as you do a really nice, neat tuck and pull your panties up until they're snugly holding everything in place, it shouldn't come loose with standard movements, at least not in my experience. And it should be very comfortable!
It might be that your tucking technique needs work.
Forgive me, but I have to use specific terminology ahead, so CW/TW: male anatomy.
The technique that I've found works great is to first pull your scrotum out and stretch it a little bit in front of you pinching it between your index finger and thumb. Then with your middle and/or ring finger, push your testicles up into the inguinal canal (the tube that they descended from). It shouldn't hurt or be uncomfortable at all! If it is, keep looking for the correct area. Once they're in there keep your middle and/or ring fingers there to hold them in place, and with your index finger and/or thumbs push your penis back so it sits flat against your perineum (or taint if you prefer). While holding everything in place and even keeping your legs pretty close together, pull your panties up to keep everything in place, and you might be done.
After this stage I usually like to use my hand with all of my fingers together to push from the base of my penis backward to make sure it's all nice and flat. Then just make small adjustments to make sure nothing is poking out the side, and make sure your panties are up nice and high and holding everything flat against your perineum. You can do basically anything except intense body movements with this tuck and nothing will come loose. Again, though, this is just in my experience, so I'm not sure what to suggest if that doesn't work for you.
Tucking into the inguinal canal is not safe.
I've never read anywhere that it's not safe. Do you have a source for that information?

There are some minor risks, but if done properly it is mostly safe. If any signs or symptoms listed in the risks section then they say you should stop and seek medical attention.
