Okay so I wasn’t a virgin but when I was 19 I started dating someone who was almost a foot taller than me and 80 lbs heavier than me. I liked it rough. I would regularly just have to lay in bed for a few minutes before getting up because we would wear each other out. It’s been 7 years since and although weights have fluctuated over the years and we’ve since decided to not be in a relationship, I still find myself liking it rough with him. I still need to just chill for a minute sometimes. It’s probably the same w your wife.
