NC for this. Will try to keep it as brief as possible.
There's an age gap between dp and I. I'm 36 he's 47. We are really happy, built a good life together, my dc love him and we are due to get married at Christmas. We get on brilliantly but our sex life is lacking.
He has been open and honest about his low libido and he takes viagra. For this reason sex is never very spontaneous but I'm ok with that. We still do it 1-2 times a month which is ok with me.
But I also know he has a particular fetish. I've seen his internet history. It's nothing disgusting or illegal (!!) but I suppose it would be considered taboo. He never disclosed this to me, I only found out about a year ago by chance. Since then I've felt shit about our sex like. I'm questioning whether he really does have low libido or if it's me who just doesn't do it for him. I've gently broached the issue of trying out this fetish together (it's not something that does it for me at all but I'd be willing to at least try) but although he seemed keen he's never pursued it. I lack confidence and wouldn't know where to start with initiating it. I've been very open and non judgemental about it with him but I sense he's still pretty cagey about it.
The other night we'd had some drinks and I jokingly asked if it was something he'd done with any exes and it became quite clear he had with one particular woman, I feel bloody awful now because were supposed to be getting married yet it's something he can't or won't share with me.
I feel like I've made some compromises already and now there's this wedge between us. I love him dearly and this isn't a deal breaking situation so please no 'LTB' comments. But I would like to improve things and have a more fulfilling sex life. Any advice?
