Does size really matter? It depends on two things.
If you’re the type of dude who walks around bragging that your penis looks like a 9 inch wrist when your shit really looks like one of Shaq’s fingers then, yes, it does matter because a female would never hesitate to put a dude in his place and burst his bubble.
Also, it depends on the female. Some females have more dick tolerance than others. Size only matters for sexually based relationships. If you’re one of those dudes who can only thrust in because every time you try to give a full thrust your dick pops out then you’re probably not going to have many friends with benefits.
But, if you’re a good dude and you actually took some time to get to know your lady you love her she loves you then no, size does not matter. But, if you’re concerned you’re not pleasuring your lady with your 5th grade penis then, eat her pussy until it tastes like nothing.
WORD.
