Go out to a bar

You want to meet new people, maybe take someone home. A few hours after eating your dinner, you get into a casual t-shirt and shoes, deciding to forego pants and underwear altogether. You then get into your car - at around 8pm - and drive to a local bar. You arrive and find yourself a stool by the bartender and order a fruity beverage. The bartender was a woman, pretty common for a customer facing position. She has brown hair, about a c cup, around 5' tall, and of a slim build wearing pretty modest clothing with little skin showing, so she isn't really here for guys.

Looking around, you see a short and feminine looking guy, around 4'10, 3 stools away. Slim build, blonde hair, crop top with nothing else, and a 4"-ish cock drinking some sweet ale. You see a group of three fairly muscular guy behind you chatting, completely nude, all of their cocks around 10" and all over 6 feet tall and their drinks vary, but they are what most would consider masculine.

Then in the corner, you see a guy of athletic build, about 6'5, brown hair, some stumble, clear skin, and - assuming he's a shower - about a 16" dick, one of the largest you've seen. He's wearing a t-shirt, tennis shoes, and jeans with his dick sticking out the fly. There are some other people around, but none of them catch your eye.

You'd definitely need to stay awhile if you want a chance with the bartender, and you'd need to get at least a little drunk to have the confidence to talk to the bigger guys.
