Now...you cannot tighten up. Why? Because you're never going to be any looser. Your vagina is exactly as "tight" today as it was before you had sex the first time, and it'll be exactly as tight even after giving birth to a baby. Tightness or looseness is a myth. Your vagina is elastic, it springs right back into the same tightness.
So, in short...you're never going to be any tighter, you're never going to be any looser. And that's just fine, there's nothing wrong with that at all. It's normal. Don't stress about it, and don't let anyone convince you otherwise.
