Opinions on until marriage?

As the 46 year old male in a happy 20 year marriage. I had 1-2 ual partners a year from the age of 16 to 28 - the 12 years befoe my marriage. A total of about 20. Some I was compatible with, others NOT. Marriage is not BASED on , it is based on love. is the ONLY thing in the world as a man you aren't allowed to have with anyone other than your wife. So if with her is bad. That part of your life is bad. And that was just not acceptable to me. I love my wife. And I loved her 20 years ago. I would not have married her without making sure we could make the part work. I read blogs from guys saying, I wish my wife would do this, or do that, but she won't. And I think, you should have found that out before marriage.
