In my opinion, age gaps in partners really depend on the age of both people. For example, if one person is 40 and the other is 55, I think this relationship is completely fine because even though they are 15 years apart, they are both mentally mature as each other. However, if this age gap was applied to a 19 year old and a 34 year old I think that relationship would be very concerning. Like yes, technically this relationship is legal but both individuals are at very different levels of maturity. Furthermore, there's the question on why the 34 year old is wanting to be with someone barely pass legal age. This can also be applied to someone who is 23 while the other is 40 as (in my opinion) there is no reason for someone who is 40 to be going for someone in their 20s. While the physical gap in the relationship is important, it's also important to consider the actual maturity of someone that age and where they are at developmentally from a mental stand point. Not to mention, the different levels of maturity ca unintentionally cause a pwer dynamic which isn't healthy ofr any relationship.
And of course if one person is a minor in the relationship and the other person isn't then that is incredibly concerning and a wholeeee different topic. These are just my personal opinions though. In regards to your situation, I think it really depends on your age and your crushes age. And if the age difference is something that you are not comfortable with, that is completely valid!
Hope this helps a little bit, stay safe!
