I am a cyclist and natural sinker with fairly lean body. Swimming 50 meters in the pool gets me gassed. Me legs sink. If I bring my legs and hip up to the surface of the water, my head is too low to breath easily. Breathing every 2 strokes is better than 3 for me. Swimming faster to gain inertia helps but gets tired fast. Swimming slow helps breathing but legs sink.
My goal is to do an Olympic distance tri, so 1,500 meters. Can anyone help?

You’re doing fine - this is a NORMAL and expected situation for anybody when they learn to swim.
As you’ve learned, it’s not easy easy as just ‘pressing the head down’, although that sort of advice does help.
A big reason that you are finding yourself so gassed is that your motions, as expected for a beginner swimmer, haven’t developed the coordination and balanced such that one movement doesn’t disrupt your body position or another motion. As a result, every stroke you take, every little kick you take will force you to expend energy to bring your body closer to ‘flat’ in the water.
There is no simple fix. You just have to stay at it, swim more, practice more. All of the aforementioned advice helps - try swimming with toys like a pull buoy with no kick at times to isolate the arms - you’ll quickly see how imbalanced your stroke is and how it’s messing up your body position. (It’ll likely feel near-impossible at first to swim with no kick.)
But you’re on the right track, with being aware of body position, and actively working on it. It’s hard, takes time, but you will progress, just be patient. Took me over 2 years of ‘serious’ swim training to even get to ‘not horrible a swimmer’, but you will be able to finish an Oly swim (albeit at a slow pace) within 6 months.
For you, swimming slowly but comfortably for the vast majority of your training, if not all of it until you get easily swim 1000+ at an easy pace no problem, is in order, as your technique is by farrrr your limiter. (I rarely say this on this forum, as most folks here are intermediate swimmers, but in your case, technique technique technique, forget about swim fitness. Lots of easy swimming, study up on drills and use them in a targeted way, but swimming as much as possible is the #1 priority.)
