For me it's just penises in general, mostly. Larger, beautiful specimens just seem 'more of a good thing'. Lol! But I do think it's a fetish of some sort, seeing I can be quite obsessive about it at times. But I'm sure pretty much 50% (don't we all love percentages here) of the member will be.
I'm currenty in a relationship with a smaller man, and I have to be honest and say it's not always as easy. Apart from his very low sexdrive, having penetrative sex is almost impossible and never lasts over a minute or so. Yes, thát small. You don't fall in love with a dick tho - atleast, I don't - and it's not the end of the world. I won't say I don't strongly miss penetration, espescially seeing my previous partner was my first encounter with larger men - but I wouldn't trade him for a larger endowed guy. Let's be realistic, there's no such thing as a perfect man.
I love toys, but it's more an extra than it is a replacement for a bigger penis. My guy doesn't seem to like then as much on me, espescially anything bigger than him. So that's not an option.
You're much too hot and sexy to have to put up with a small penis and low sex drive. Get out of the relationship and have some fun with a guy who can satisfy you sexually.
