Honestly, I've always thought shaving underarms and legs to be totally bizarre. I have done it, especially as a teenager, but I rarely do it now. It has never impeded my ability to attract men, except for possibly weeding out the types I'm not interested in anyway. I do find that underarm hair will hang on to smell even when washed with soap, and if I'm going to be in a very sensitive situation, I'll shave for that reason. But it's pragmatic, a concession to the culture I live in.
