I think Dr. Mark has alreay hit the mark with his answer. But I understand also from your request for 10 experts to answer whether they would do that themselves or not, that you're pretty young and worried about making yourself vulnerable to rejection and embarrassment by admitting that a shade of lipstick turns you on. I would ask my wife of 28 years to wear a fetching shade of lipstick, and she would try it because she wants me to know that she likes the prospect of turning me on, and wearing one shade or another of lipstick is well within her flexibility of how she wants to look. There wouldn't be 50-leven shades of lipstick on the market, with another 20-hundred coming out each year if it weren't well know in the fashion industry that men are turned on by how women look.
(Your concern is not unfounded though. It is possible, that some young women might misinterpret your interest to imply that they had to change their look in order to be alluring to you--if they were very insecure about whether they were attractive enough to turn a guy on or not. If you aren't able to feel turned on enough without the new shade of lipstick, it's possible you're not comfortable enough with her feminine otherness (compared to yourself) for your sexual feelings to emerge; so I'd suggest you keep on getting more comfortable emotionally through familiarity and erotic foreplay--and don't worry about whether you're keeping up with what the other guys say they're doingt or whether you're doing what your girl wants you to do. Developing your sexual young adulthood is an awesome and shaky adventure.)
And almost all young men have gotten turned on by some fashionable ways that women look in advertisements (which are meant to turn men on, so women will know what to do to turn men on, since they want to feel desirable when they dress up) before they ever got a chance to start having real personal relationships with girls. It's 100% likely that every young guy is aware of some ways of being turned on that he hasn't yet been able to experience with a real girlfriend. So he's prone to embarrassment until he's able to cross the puberty-2-adulthood bridge between what is essentially autoeroticism focused on imagery of women over to mutual sexual interaction with a female. Those of us who as young men DON'T follow the path to sexual relations that uses being drunk enough to obliterate our ability to feel shy, embarrassed or ashamed can have many experiences of extreme awkwardness when we are trying to communicate about what turns us on -- and that's what you seem to be writing about.
Here's some news from the other side of the gender gap: young women have the SAME issues with being very worried about revealing what turns them on to a boyfriend, but their relationship to sexual arousal is different, so what they do is likely to be different too. Since they can receive a young man's sexual excitement without being ready for orgasm themselves, they can concentrate on making sure he is excited WITHOUT needing to communicate to him about what would make them excited enough to reach a climax--and they can act like they're satisfied when they haven't had an orgasm, and in fact they may not even know what their own female orgasm would feel like. So the young woman may face other uncomfortable issues, most notably, that she may worry that she has to make sure she's sexually attractive enough to turn him on, which is a very obvious result, whicle she can act like she's very turned on without anything showing that she can't voluntarily control--like an erect penis. But she may be able to avoid ever having to try to communicate what would turn her on to her boyfriend.
So you can end up feeling you're the only one taking that kind of a risk (of being thought of as a wierdo). So I suggest you take the opportunity during a nice sexually intimate moment to ask your partner what turns her on--or kiss or fondle her very carefully somewhere that excites you and then whisper in her ear to ask if she likes that. If you can start giving her the chance to adjust YOUR actions so she's more turned on herself, then she'll be happier, AND she'll be more inclined to want to jumpstart your batteries by wearing what excites you--because she'll be satisfying her craving to know that she's everything you want at the same time as she's getting to guide you towards more intimately connected sexual body-dancing with her.
(In fact, beginning in the late 1960s there was a strand of women's sexual advice books that was teaching women how to learn what turned them on and then how to communicate that to their partners, so that more of them could achieve the orgasms that Masters and Johnson had discovered were actually more numerous, dramatic and fulfilling than men's orgasms. Sexuality is in fact an awesome private arena that most of us are not prepared for at all, and it also intensifies the energy that bonds us to each other in love to an extent we could never expect until it has happened. So it's very appropriate that we should be awkward and frightened about it on the way in.
