Is it pedophilia if a 19 year old pretended to be 15, while their partner is the same age as them?

Pedophilia is specifically defined as a sexual attraction to prepubescent children, typically those under the age of 13. In the scenario you've described, where a 19-year-old pretends to be 15 while involved with another person of the same age, the situation involves individuals who are both legally considered adults in many jurisdictions. However, the dynamics of deception can complicate the ethical considerations of the relationship. If the 19-year-old's deception causes harm or violates consent, it could have serious repercussions, even if both individuals are close in age. Legal implications can also vary based on local laws regarding age of consent and the specifics of the situation. It's essential to approach such situations with sensitivity and a focus on communication and consent. If you're looking for specific legal advice or have deeper concerns, consulting a qualified professional may be beneficial.
