Some people really frown on the big age difference (power dynamic), but as long as you were kind, took your time and it was legal & consensual—I see it as the younger guy being very lucky.
When I was 19, in college and freshly out of the closet, I had a daddy who was 48. He knew I was a virgin and had 0 experience with guys. He was kind, patient, and we both knew exactly what we were doing. Everything was upfront. I look back on him fondly as he really showed me how to take a good sized cock, how to give good head, how to clean/douche, and even how to switch hit, and top him. I kept in touch with him years after I moved away from the college town I met him in. I always felt very lucky, because I could have lost my virginity to a young dude who took things for granted, or someone who had no feelings for me at all.
