<human>: Can you succinctly summarize the text in 1-3 sentences?

So I've been seeing this girl for about two months now, and we feel strongly about each other already. Neither of us have been in a real long term relationship before, so we're taking things slowly. But a major roadblock in moving things along is how I don't show enough affection for her (whereas she's very expressive). She's brought it up a couple times already, and apparently I'm hard to read.

The problem is, my dad was never very outwardly affectionate towards my mom, and I was taught to hold in my emotions and "be a man." Even though I've given up those ideas, it's still difficult for me to show the affection I have for girls. My previous two (sort of) relationships both fell apart mainly because of that. I've been improving with my current partner, but I need to know how to be more affectionate. She knows why it's difficult for me, but I don't want to make her wait or have to guess, especially because I've never felt this strongly about a person before.
<bot>: Have trouble showing affection, but want to for a girl I really like, so I'd appreciate ways I could show it.
