So, my boyfriend is in the Army and he just came home for Christmas. Yesterday we had sex for the first time. It was his first time ever. I took his virginity. We had sex for about 15 minutes, but after the first 10 minutes he went soft and he never "finished". My brother and I are super close and he told me that's pretty normal because guys usually get nervous for their first time. I'm just worried that he isn't "in love" like he says he is. Any advice?
