Its not about whether you have sex with men or women its about what sex means to you. Suppose you have sex with a number of men and dont get pleasured that much either, which could happen.Take more time before choosing a partner. Understand the risks too of same sex relationships, compared to straight relationships. For example, lesbian women are four times more likely to get cervical cancer than straight women later in life according to world health organisation research. Do your own research. dont listen to people who say everything will be fine, and just do what you feel, as its your body, not theirs. Whether a man or woman, its best to avoid a lot of partners for long term health.
