If he is literally able to last for 2 plus hours, he is almost certainly on Viagra, probably to compensate for age or a mid life crisis. If it feels like 2 plus hours, and not in a good way, that is also a problem.
This sort of thing should be so easy to fix with open communication and an open mind. In a HEALTHY relationship, you could try lube, him cutting back on masturbation, more foreplay, toys, therapy, counseling, hormones, etc. However, it sounds like your husband cares more about showing off his virility than your sexual comfort. He paints you as the problem, he equates your not wanting to take a 2 hour session of intercourse as you not wanting him period.
If you’ve been together for 10 years and this issue is just surfacing, I am going to assume he’s on Viagra now. I am presuming this was never an issue before because he never lasted so long before.
Here is the bottom line. You can only do so much with a partner who doesn’t care about your boundaries, your pleasure or pain, your comfort. You can’t tame and train him like Dany taught her khal to be a gentle lover, that’s fiction (written by a man, at that). Your husband does not seem to be receptive. You’ve already told him you can’t take it that long. His thought is, “you’re the problem, why can’t you accommodate his desires? There is no possible way he is the problem.” This is scary, toxic thinking.
When one person experiences discomfort during sex, that is not a yours or my problem. It’s an us problem that only we can resolve together, maybe with some professional help. Maybe you have some kind of condition, maybe you’re too dry, maybe your hormones are low. But you can’t just “fix” yourself to suit his wants. He needs to adjust to your needs too, but you’re already at the point where you dread sex. His unwillingness to cater to you is creating a vicious cycle that exacerbates the incompatibility.
A man who thinks he is entitled to your body, thinks there is something wrong with you and you alone if you don’t take everything his way or the highway is a dangerous man. You are not a sex slave.
I would reevaluate this relationship very seriously and quickly. It sounds like you tried the open communication route, and now you are resorting to delay tactics. That’s no way to live. There’s nothing wrong with you, Bee. He’s the problem because he won’t work with you; he expects you to do all the accommodating. Our bodies evolve and change with age, and sex should be about working as a team to achieve mutual pleasure. This man is treating you like a blow up doll.
Please do not let this go on. You don’t deserve this gaslighting and physical torment. He’s gotta go.
