I can't stand lip gloss or lip stick! Not only do I not like it, I can't wear it. I have not yet found a brand that doesn't make my lips ddry or break out. I have really sensitive lips and can only use certain brands of chap stick. Do guys like gloss or lip stick or just plain lips?
It depends on the guy, but personally, I don't think I spend an enormous time staring at a girls lips because they're so small compared to the overall size of the body. I just don't think it's a thought that crosses a lot of guys' minds.
This wasn't really your question, but it could help you. Clinique has some lip balm type stuff (like in a tube) called "Superbalm Moisturizing Gloss". It's allergy tested, and fragrance free. It really hydrates your lips, gives them a bit of shine, and won't make you break out. hopefully.
