A lot of women have some degree of discomfort with how they look physically, especially when naked. It can be difficult to become more comfortable with how you look, but try focusing on a part of your body that you like. Think about different parts of your body and how they look right for your body.   Focus less on what your body looks like, and more on what it can do. If your partner is critical of how you look, assert yourself by telling them that you find their comments unsupportive. When engaging in intimacy, communicate your needs to your partner clearly. Loving yourself and honoring your sexuality means telling your partner what you like and what is off limits.   You can say something like, “I like when you touch me there,” or “I like when we cuddle after sex.” If something is uncomfortable, say so. "I'm not comfortable with that" or "That hurts" are very reasonable things to say. Don't be ashamed of wanting to have a sexual side.  Empower yourself to embrace your own sexuality in whatever form it takes, and choose partners who facilitate and uphold healthy sexual practices. Just about every woman, at one point or another, encounters a person who wants to take advantage of her sexually. It is important to learn both how and when to say no to someone who is making unwelcome advances at you. Do not let sexual assault go unnoticed. One in five women and one in 71 men are raped in their lifetime. If someone forces themselves on you, reach out for help. Society has taught women to feel ashamed or embarrassed for being molested or assaulted, even going so far as to claim that some women are "asking for it.” Letting someone get away with a sexual crime teaches them that it is okay to do it again in the future. Remember that reporting these kinds of acts is not just for your own good; it could prevent the person from harassing others in the future.
