Now, while I wouldn't express myself quite like
@William67, I'll have to admit that I understand his frustration.
Furthermore, the fact that he (as a male) resents dating woman with multiple parters in the past, is actually quite atypical. Usually males are the ones who are the most promiscuous. Now, our brother here is obviously not afraid to speak his mind, but I'm not sure if anyone here would have protested if William67 was a woman, and a tad more soft-spoken.
For here is the thing, many Christian women seemingly agree 100% with William67 about this! If you're a guy with a past, Christian women will apparently more often than not, hold your past against you. For instance, check out this thread, where a young, nice Christian male admits that “good” female Christians won't touch him with a ten foot pole:

We also had a thread last summer where the question was, “would you date people with a past”, and the consensus seemed to be “it depends”.

William67 isn't alone in stating that sometimes it's difficult to forget someone's past, even if they have repented and are forgiven by God. I had a quick look, and there are many threads like these on this forum. I think he actually describes a real phenomenon; if you're a person who have avoided sexual sins, it can be difficult psychologically to date someone who is, ahem, experienced. For some guys the mere thought of marrying someone who've had multiple partners in their past, is actually quite terrifying!
Here are some relevant threads about this:

To sum it up, William67 isn't always the most diplomatic person when it comes to the way he expresses himself, but I think that perhaps we've given him too much flak in this thread. We're talking about his feelings here, and it's not really possible to argue with emotions. We'll have to respect that he feels this way, in the same way that we have to respect all those women out there who are scared of guys with a past.
