Dating in general, including online dating, is very competitive because men generally look for women within a certain age range (but has to meet other criteria as well, such as attractiveness, wife-material, can bring in an income, etc.), and women generally look for the "top" tier of guys based on status/looks. This is based on dating research data.
Recently an Uber driver (mid-30s) was telling me he dislikes women treating 40 as the new 20, because that doesn't work with the biological clock. He was saying men who want children have limited options nowadays as a result. He (and also a guy friend I know) want educated women who will bring in an income. I think that is the problem, guys want youth, looks, AND education, and income potential. Education/income is more of a criteria now for educated maybe all guys (before I don't think it mattered). This particular Uber driver was Indian. He was saying some of his friends are looking into marrying women from Colombia or India, but he personally isn't interested in that because marrying that way brings a different set of problems.
Bottom line is, both men and women, Christians included, are looking for someone who meets all their checkboxes, so this makes things complicated. I definitely had more attention online when I was younger, I have way less views on my profile now because I am over the age range guys seek.
