I just...why not? Like, really, besides the whole "god will be pissed" thing, what is the downside to having sex before marriage, and with other people. I have been with other people, and my gf has been with other people. I don't care, she doesn't care, so why should god care?
I'd almost say the opposite if OP, that it's not a testament to your strength, not having sex with anyone before your spouse, but a detriment, because you have no experience, no bar, nothing to measure against and learn from, meaning that you might not be fulfilling your significant other. Not that sex should be "practice" but I think it's safe to say that those who do save themselves, might not be seeing the true importance of sex in a relationship.
