Exactly the same here. My parents have died and I nursed them through long and horrific illnesses, and my husband left me in recent years. All this has brought about a great desire to live my life while I can, before I come down with the family cancer myself. I truly feel like every day is numbered. I went on a dating site and fucked a handsome paramedic, a Porsche-driving millionaire and now I've been FWB with the sexiest, sternest, filthiest teacher for about three years.
None of that is as good as it sounds because they were/are wholly unsuitable in every way, so they were all short-lived except the FWB, and I don't see him much because we don't live near. Plus he's just a good-looking perverted sleaze-bag, which is why he's so good in bed. You wouldn't want to do commitment with him though.
I find it very hard to meet men who I both trust and fancy, but although I'm heartbroken about losing the good parts about my marriage, he was a wrong 'un, and now I'm glad to have my freedom.
OP, you must spice up your sex life with your husband. That's the answer. He might have low testosterone, you know. That's common in men that age.
I'm seeing FWB tomorrow. I was concerned because he needs some surgery and he went kayaking today (school hols). I said are you OK for tomorrow, and he goes "If I can kayak for two hours I'll have no problem fucking you for three." 😱😂
Light your DH's fire by getting filthy, OP. I dare you. If I was still married, that's what I would do with my DH. Shock him, surprise him, tease him. Be a little mysterious. Start by wearing some bad-girl eyeliner around the house. Got it?
