Im 23 and my boyfriend is 18 and still in highschool its only 5 years age difference but is that wrong?

The age difference between you and your boyfriend is relatively small, especially considering you're both young adults. However, the dynamics can be influenced by his being in high school while you are already in a different stage of life. It's important to consider factors like maturity levels, life goals, and power dynamics in the relationship. As long as both of you are consenting and comfortable, it's essential to communicate openly about your expectations and boundaries.
