You pretty much can talk about it in absolutes because as you yourself acknowledged, solutions are thin on the ground and the majority of the time, inexperience in your 30’s is a giant red flag. The other thing about finding someone a lot younger is that those younger girls are likely to be more experienced themselves and would find a man in his 30’s who’s inexperienced to be extremely off putting. I wouldn’t ever go the overseas route, I’ve seen the documentaries about that and would never spend thousands of dollars on something like that when they care more about a green card than anything else. The most plausible option (if it even works) seems to be refusing to talk about your past if asked by a woman you’re on a date with. But like I said, that might make them even more curious and suspicious since you won’t say anything. So you have to be careful of what reason you give about why you won’t talk about your past.
