This is why I always tell guys to take their time with the woman they desire the most. Yes, she is hot, pretty, and appears to love sex but stop, look, and listen. Hear the conversations that are happening if you are part of that friend group. If she is a size queen, you will know it. I had a beautiful first wife (RIP), and through some miracle, her depth and my length were such that I would hit it gently. Perfect fit.

Don't be in such a hurry. Women and men who jump from one penis to another often (and there is nothing wrong with that) are targeting, enjoying, and moving on. Look for the signs. Listen to hear if she talks to her friends about every conquest, good or bad.

If you are looking for a long-term relationship, remember two things: all 5 senses will determine if she is the one or not, and stay away from the girl who is far from ready.
