My boyfriend is 65 & I am 46. We are crazy in love with each other. Neither of us have ever had such deep feelings for another before. We make love usually daily....I always have multiple orgasms & he isn t able to due to a males recovery time. However, when he dies reach orgasim immediately following he is very fatigued....simply exhausted. He said that he had never been like this until me. He also has what he calls after shocks where he feels it from his head to his ties and has some jerking and shaking with it. He says that it seems that it has become more intense as his feelings have become more intense for me. He literally has to lay down immediately no matter what position we are in and once his body calms down he goes to sleep. Is this normal or is it cause for concern?
