Gosh, that is quite an age difference, isn’t it? Never the less, you know what they say - age knows no boundaries, and I’m sure you will both be very happy together. Now, I’m not an expert in these matters being unmarried myself, but all I can suggest is that you try not to look at it when you touch it, dear. Not until you have your gag reflex under control.
Wishing you both a long and happy marriage.
