Depends on my surroundings and location..........

Gym or Public Pool........ where 'appropriate coverage' (no thongs or half backs) swimwear must be worn...... White, lined 1 inch side Asics trunks.

Spa Pool......... (depending on other clientele,) white, unlined 1 inch side Asics trunks or conservative dark coloured thong.

Public Beach....... Thong. Brevity of which depends on who is about.

Quiet Beach/Private Pool....... Thong, a small thong.......and I do mean SMALL!!!

Wherever I am, I wear usually briefs with a bulge in the front. When I am in a spa or in a private pool, I wear see-through speedos (small briefs or thongs)
