can anyone explain me this tweet i translated but didn't quite get it ?

I was gonna lose my virginity... As I undressed she saw how small my little friend was, I was very ashamed. But, she told me everything was okay, since compared to sentinels it wasn't that small. That time I realized she was the woman of my life. (idk if it is the same in english but calling a team small is the same as calling them bad)
