recently wanna get back to swimming so went shopping for swim trunk

I used to wear briefs/"speedo" style swimwear when I started swimming and pretty get used to it.. that was a long long long ago...it was like in another time dimension

and since working, does not exercise and now put a few kgs of weight, still in normal BMI range but you know la.. fat gathers at my waist and abs..ughh

yesterday went shopping for new swim trunk, tried on the more 'conservative' jammers which I nv worn one before. was shocked at how uncomfortable it was despite I am wearing the size according to my waist. I feel like my thighs are getting chocked and lack of support at the nether region, i prefer the suit to lift away instead of pressing them between my thighs.
Some more my wife said that I looks shorter(i am not proud of my height) and like uncle

okay next,
Tried on the 'square-cut' type.. a lil better/forgiving on the thighs but i do feel like the fabric will roll up and I still find it lack of support and the pressing issue annoying

tried the briefs style.. straight away, it feels at home. Love the freedom and support.. but totally no confident to show more skin in front of people now and I am looking for a general purpose swimwear that if needed, to be wear to the pool, waterpark and beach with friends/family/colleagues etc...

so at the end no buy :/

what is your guy thought about this dilemma?
