Outside of you neglecting to experience this before marriage, without the possible ethical and soul-crushing implications of your request, you have two options, assuming traditional toys are out of the question:
-Toys/devices that artificially augment his size (such as sleeves or extensions that he inserts himself into, essentially a hollowed-out strap on), but will not feel like “the real thing.”
-You tell your husband you want to experience a large penis. From another man. That you’re not married to. Think about that.
If you value the marriage, be open about it, although, the general premise does not elicit he may be up for that. Explore swinging, maybe, but again, I don’t know the dynamic of your relationship. The other issue is satisfaction. What happens if you’re surprisingly fulfilled (no pun) by that supposedly “greener grass?”
Do you have religious, social, or moral roadblocks? From the sounds of it, you were likely a virgin when you married him. Assuming that, you are likely religious. Assuming you’re religious, your marriage is likely extremely important to him and the surrounding families. What a pickle. I could also be wrong, but, I’m having to deduce this.
You could also simply cheat on him. That solves the problem, right?You need to reflect deeply on your own values, your marital dynamic, ability to communicate, weigh your priorities, and calculate this risk in exceptional detail. You can potentially destroy your husband’s ego and self-esteem just by bringing it up. It could ruin your marriage. He may never want to perform for you again. If he’s not okay with it, it could potentially linger in his mind for the rest of his life, and if he finally represses it, he could then turn angry. Or, he could be accepting of your desiring need to sleep with another man (and I articulate this basing the situation off of a very traditional, vow-specific marriage).
There is no good answer. You have a significant fork in the road, and from your vaguely articulated situation, it doesn’t sound like it will turn out favorably. Especially for your husband.
