WAKING up on a Saturday morning, Beatrice Gibbs takes one look at the naked stranger lying next to her before quickly putting on her clothes and leaving.

As the 22-year-old make-up artist walks home, she texts her boyfriend Adam Gillet to tell him she’s on her way back.

Beatrice feels no guilt as she walks through their front door – because Adam knows exactly where she has been and what she's been doing.

The pair, who have been together for two years, have a one-sided open relationship.

Beatrice can sleep with who she wants, when she wants, despite Adam, 27, not having the same privileges.

They came to the controversial arrangement after Beatrice threatened to leave because she was unable to resist other men.

Beatrice, from Milton Keynes, Bucks, explains: “I love Adam, but I wasn’t ready to settle down and commit to just one man.

“I said I had to break up with him so that I wasn’t unfaithful. I didn’t want to hurt him by going behind his back with someone else.

"He was devastated and suggested we stay together but I could sleep with other people, as long as I told him who and when.

“It’s the perfect situation. I have a boyfriend I love but I also get to have fun with other men when I want to.

“Some people might think I’m having my cake and eating it but we are happy and we’re not causing anyone any harm.”

Despite insisting she loves Adam, Beatrice never feels bad after sleeping with another man.

She says: “I don’t feel guilty as we both agreed to our open relationship. I know it must be difficult for him but it’s the only way we could be together.

“The morning I see him after a night out I do sometimes feel a bit bad, but after a cuddle and a chat it’s just us being ­normal in our usual relationship.”

Adam claims he has got used to their arrangement.

The warehouse worker says: “I really like Beatrice and I didn’t want to lose her. I’m happy for her to enjoy herself.

"We decided this is the best way to take the relationship forward so I have become used to it. I’m not really interested in chasing other women and I know if I did then Beatrice wouldn’t be happy about it.

“I want to keep her in my life and if it takes allowing her this freedom with other men then so be it.

“I did feel jealous to begin with, especially after the first time. I still feel a pang of ­jealousy when she mentions what she has been up to, but I keep it inside. I’ve learnt to deal with my feelings about it.”

The couple met in February 2014 at a mutual friend’s birthday party in Oxford.

Beatrice says: “We went on a pub crawl and I was introduced to Adam by a friend. We got chatting and he seemed really nice. He was very flirty so I assumed he was keen on me.

“We both got very drunk and slept together, but we didn’t see each other for a couple of months after that.”

After Adam got in touch with Beatrice on social media, they met up again in April 2015 and have been together ever since.

She says: “We started dating and would talk for hours every day on the phone. I really liked him but I wasn’t ready to commit to him 100 per cent.

“I really enjoy attention from men and I knew I couldn’t resist a snog or even sex if I wanted it. I couldn’t trust myself to be faithful.”

After just a month, Beatrice decided to end their romance.

She says: “I was sad but I didn’t see any other way. When I told Adam he was so upset, but when I explained my reasons he calmed down.

“He suggested we could have an open relationship where I could still get with other ­people as long as it was only physical.

“I was surprised and a bit apprehensive at first as I didn’t think he would be OK with it.”

She decided to give it a try and for the last 18 months has been dating Adam but kissing and sleeping with other men.

She says: “I couldn’t tell you how many guys I’ve kissed — sometimes it is up to six a night, but although I love the attention it doesn’t mean anything emotionally to me.

"I’ve slept with five ­different guys since we started the open relationship.

“Three have been one-night stands and one is a regular who I sleep with around twice a month.

“He drinks in the same clubs I do, so we hook up at the end of the night if he hasn’t gone off with anyone else. I don’t really have ­feelings for this guy but I enjoy the sex.

“I tell Adam about the guys although I won’t go into detail about the actual sex. Adam is so caring to give me the freedom to do what I want — it makes me love him even more.

“I couldn’t handle it if he did the same to me and was with another girl. I would hate it.

“We still sleep together and have an active sex life, so it hasn’t ­damaged the physical side of our relationship at all.”

Beatrice adds: “My parents don’t know and I don’t talk to most of my mates about it. I think they’d be quite shocked. But it works for us.”

Adam says: “It takes away the worry about her cheating on me, if I let her sleep with other people she comes back to me.

“I don’t mind her talking about it if she wants, although it’s not my favourite choice of subject.

“I’ve told a few mates and they think it’s a bit strange, but we don’t care what others think — it makes us happy.”
