Going to be graphic here and fairly blunt. It wouldn't bother me in the slightest as a physical issue. The no testicles issue shouldn't bother any decent girl unless she wants children. You may find more women who are already mothers or who are openly infertile are more 'reliable' in that way but at the end of the day if you're up front that aspect shouldn't be too difficult to get around. As for the "small" penis, to quote an age old saying, "It's not the size, it's what you do with it". Most of the male and female sensory nerves in their nether regions are at the very 'edge' anyway - with fellas having a sensitive tip and the lasses feeling more around their opening and clitoris. What might put people off is if you're 1. obviously so self conscious or cowed by it that you can't loosen up, have a laugh and plod on or 2. if you're not willing to try or inexperienced/unlearned in other ways of stimulation or unusual positions that aid penetration/pleasure including from other areas than the vagina. Most women feel more strongly about clitoral stimulation than penetration although some do go for size. I'd personally pick an experienced and inventive tidger over a pomy sized penis without the excitement or effort. Read up if you need to, loosen up and above all don't be so scared as to think all women are shallow. It's not just your knob they're interested in, have confidence in yourself (blag it and pretend even if you don't) and they will be attracted to you.
