Since you have a large memeber, I don't know well what to recommend you, but try the R20. I got it, the inner structure is kinda nice, but too big for me, but I think it will be a good fit for you.http://en-nls.com/pict1-15738?c2=9999
As for lubes I've tried PePee Wankers, not bad, but I think you can try buy Peace's, it's the recommended by NLS.
I also recommend you make an order of 60€, don't just limit yourself to 1 onahole, because you will save money in your next purchase in shipping. Try to not buy too many things because you can get customs. I'd recommend 2 onaholes and 1 lube, make sure you buy of the big bottles, you should not run out of lube, because then your only option would be saliva, and that sucks (do not use soap).
