I think that 6 sexual partners at 35 is a good number. It varies from person to person so much. I'm 25(female) and I've had 6 also. Some of my friends think that's slutty (yes, I'm from a very conservative part of the world) and some don't bat and eye at it. I say, whatever, who cares. My husband (who is 43) has had literally hundreds. Does this bother me? Not at all.. it was during a phase in his life when he had some money and was living in South America.... and beleive it or not it was mostly with prostitutes... I don't care, he's been tested for everything under the sun and he's clean (luckily). I think that when he's hard it's like 7 inches at least. I haven't had tons of partners but he's bigger than any of the ones I was with. Do I think that it's really about the size? Not really and I think that you shouldn't feel inadequite at 4 inches. I'm of the opinion that it's how to use it that really matters anyway and in all honestly I would love for my husband to be 4 inches sometimes because sex with him can be painful - painful = no pleasure for me by the way. Also, if you're with a woman who is so fixated on penis size then maybe you should find a new one who cares more for YOU than your organs. Seems like you'd be happier in the long run.
