To tell or not to tell..?

Okay so I know this is my first post but I feel the need to make this post about something I’m sure all of us females have done. Faking an orgasm! That’s right ladies, faking the big O. So the reason I choose to write about this today is because of a conversation my friend and I had at lunch the other day. She has been fooling around with a friend of hers for a few weeks now, everything was good in the bed until a few days ago. So were sitting there eating our cob salads and she leaned in close and asked..”Do you have to fake the fact that you like it?” A little puzzled I looked at her and asked “are you talking about my salad?” She then proceeds to explain to me the situation with Harry. Apparently a few nights ago they were at dinner and they had just finished their main course, he looked at her and placed his hand on her thigh and said “you look amazingly sexy in that skin tight dress.” That was enough to get her going. She gestured for the waiter to bring the check and they quickly left the restaurant. They drove to his house which was three blocks from the restaurant and things heated up quickly. After they got in the house all bets were off. He ripped her dress and began kissing her neck, her sweet spot. They took it in the bedroom and he began doing his thing. After of about 20 minutes she just wasn’t feeling it. It’s like all the heat had just disappeared. He was still going at it hot and heavy so she did what she thought she should do…Fake it! So this brings me to the point, should you fake it or just be honest? If you be honest it will crush him, if you fake it, it will boost his ego and possibly make him want to come back for more.
