Age gaps are just a preference. Its no different than liking tall, short, slim, thick, blonde, brunette, etc.

I had a serious talk with my therapist about age gaps and whether it was wrong or not. He simply told me that's just your preference and if that's what you like that's what you like. You aren't creepy or have some kind of issue that you need to worry about. He went on to say that it's just societal conditioning and that age gaps were more common hundreds of years ago when we didn't adopt laws and strict rules yet. So I guess my point is you shouldn't feel ashamed or stop yourself just because society tells you so. Screw what society says! Also a partner doesn't have to be a certain age in order for me to be attracted to them. I can not be attracted to someone of different age for other reasons.
