Wesley Benton, pilot: If I stand in front of the mirror naked, I think "Eugh, that's not very attractive", but women's bodies are lovely. A major part of that difference is their breasts. I used to love big breasts, I was obsessed with them, but now I think I'm changing. My current girlfriend has no breasts whatsoever, but it doesn't bother me.
George Andersen, unemployed: If you look at the likes of Demi Moore and Pamela Anderson Lee, they look unnatural. They defy gravity almost. That's too over-the-top for me. A lot of men do go for bigger breasts - it's a macho, laddish thing. But I think on the quiet they might prefer smaller ones. It's all about proportions.
Bob Trant, mini-cab controller: I can't help noticing a woman with a big pair of breasts if she's walking in the street. But it can be a hassle if you are going out with a woman and all the other blokes are staring at her front. Big breasts will probably always sell things because it grabs your attention - only the attention of the blokes, though.
Justin Greetham, photographic special effects expert: I must admit I do like a big pair of breasts, they are more comfortable - there's probably a link with childhood. But I don't know if it is a key feature behind a relationship.
Simon McQueen, art director: In the case of bra adverts, the image has to sell the product, show what it does and what it looks like. I don't think the women on the bikini adverts at the moment wearing the bikinis are top-heavy. They're sort of average. A lot of men might think big is better, but there's big and there's ridiculous.
Paul Temple, postgraduate student: Big breasts? Absolutely. Can't beat them. Some people say that it's personality that counts, but not for me. I think men in general definitely favour big breasts. Without a doubt.
