I am bisexual. Getting hit on by men or women is totally flattering for me. You say you aren't interested in being with women because it's just sex. Do you mean it would be just sex for you? Because many lesbian couples have normal relationships, kids, etc.

Does it bother you when men hit on you? Because you keep saying you are tolerant and yet you are only mentioning women hitting on you.

I would say a simple "thank you, but I'm not interested" would suffice with both sexes. Beyond that its harassment. Also not every compliment is a come on so I might gently suggest you read too much into it at times.

I'm sure homosexual people get hit on by straight people all the time. It happens.
