You tried to do something sexual you thought was super-sexy but the other person thought was weird, silly or downright gross. Something one partner of yours thought was the hottest thing ever turned out to be something that, when you tried it with another person, bored the pants not even off of them, but right back onto them. Your biggest turn-on is someone else's buzzkill.
In any of these situations or many others like them, you might feel like you were bad in bed or someone else might think that about you. Here's the biggest thing to know about that, before I say anything else at all: When sex is consensual, we all have the right to be our own idea or someone else's idea of who or what is "bad" in bed. Sometimes; anytime. That's because we're human.
