I often hear from lesbians who don't enjoy certain sexual activities. "Is there anything wrong with me?" they want to know. Especially if they're newly out, they wonder if they'll be able to find someone who is compatible. This week I got a letter from a young lesbian. She's had sex with men before and didn't like penetration. She has a fantasy of what it's like to be with a woman, but wonders if her preference for not wanting things inside her makes her weird.
