It is normal to feel self conscious when you wear Speedos for the first time in public or when you wear a new and briefer pair than usual. You may be sexually excited by doing this and be looking around to see if anyone is noticing your bulge or you may just feel shy. If you think you may be the only guy about in Speedos you will be looking out just in case. If you are (nearly) the only guy in Speedos people will be looking at you, some in approval, others disapproving but most just in curiosity, wondering if they might dare to do that. Giggling little girls are a problem, just because you aren't interested in them doesn't mean that you aren't exciting them.
When you see other guys in Speedos you of course will want to look at them, and they will look at you. After a while though it will feel normal, just what you happen to be wearing on a nice sunny day while having fun, enjoy it.
Saw a YouTube video of a guy in a black thong buying beer and gas (petrol) at a service station and shouting at everyone as he went around. Looked like an annoying idiot, I didn't like his excessive tattoos either.
Wear your Speedos in public and people will get used to it but prance about making a noise and you would annoy them.
