English: How you choose to have sex is up to you and your partner(s). What’s most important is that you and your partner(s) feel comfortable and that whatever you’re doing feels good. If something doesn’t feel okay, it’s important to talk about it.
Sex’s often portrayed as a dick in a pussy, and this is what people often refer to when they talk about having sex for the first time. But this doesn’t have to be the case since there are an endless variety of ways to have sex. For example, there’s oral sex, anal sex, fingering, rimming, pegging, mutual masturbation, petting, etc. You decide how you define sex, what’s right for you and what you want to do!
