Is ten years a big age difference in a relationship?

I thinking about dating a guy that is 10 years older than me. Some people say that when there is a huge age gap like that, then the woman has daddy issues. I wonder if that is true, because this guy seems to be genuinely the right fit for me. I've had some quite toxic relationships in the past, and have worked through my issues and this one really seems different and healthy compared to the other ones.
