Married but have had the guy who works for my husband..stable fun?

I'm a 25yr old woman. I got married 8 months ago. My husband is 56 and is away on business alot. Hes a good man. I have everything most woman only dream of, fab house, my own car, i dont work, my days include gym, spa treatments and shopping, so marrying him was a good option for me. In one sense. But...theres one area he doesnt fulfill me in...the bedroom. He thinks i only had him, but i told him that coz i knew his moral persepctive. I've had dozens. I've a very high drive and with other men, used to do it twice per day. I'm afraid i've now started getting that type of comfort from a young 21yr old who works for my husband looking after the horses. Its happened 5 times this past month...usually in the stables. He is gorgous and so well endowed ...and filthy...treats me like i like it. However i made a big mistake. I went out to him dressed in stockigns, suspenders, backless panites (no bra) and i'm huge on top. He loves that and gets such kick out of my big tytts...husband doesnt notice really. I walked into the barn, only to be met by a different worker. I bluffed my way out of it saying i wanted to surprise my husband....everyone knows hes away for 3 weeks. Help...am really worried, will the staff gossip? I'm getting filty texts from a new number..making references to 'back door'. The only thing i can think of is me and that guy did last week.......Help, i dont wnat to loose my marriage but i dont want to give up my 'stable fun' with my young stud barn boy.
