Itās a misnomer to say that people who are not touchy, or who are private about it, are either unsexual or are hiding their love. You and your wife sound like youāre just being yourselves, which is fine. Growing up I saw a lot of different people and parents, from all different cultural backgrounds and social strata, as well as different personalities. All these things influenced whether Mom and Dad showed their love by hugging and kissing in front of the kids, or showed their love by having a spirited conversation and reserved the hugging and kissing for the bedroom.
My father was an extremely reserved WASP. He would give my mother a kiss good morning and a kiss goodnight. From what I understand she had asked him at some point to please do that because she thought it was a nice habit and made her feel appreciated. He willingly made sure to do so because it made her happy. But he would not have come up with that idea on his own. It wasnāt his culture - when we visited in his part of the country we saw dozens of men who acted just like he did. But the love between my parents was obvious from the fact that they spent a lot of time together and talked, interacted all the time, etc. without touching a lot.
It didnāt have much effect on my own preferences for how I wanted to act with a boyfriend though. I would say my parents behavior towards me personally, meaning that they both would frequently give me a hug or other physical affection all through my childhood, was more of a factor.
