Ive had the MASHO, XS, and S Limpy (among many others) and I would recommend either the MASHO or the XS limpy for a first time packer. The MASHO I had a long time ago and don't remember well because I ended up moving on to other packers, but it was very forgiving for learning how to position a packer. The XS Limpy I got almost a year ago and it was my daily packer for a good long while despite preferring larger packers before. It has since been replaced as my daily packer by the thing I'll talk about next:
If you like packing and decide to 'upgrade' (whether just to a higher quality or literally to a larger size) I would recommend Reelmagik basic packers in SOFT. I have the original firmness as well and while I liked it, it was a bit firm, but the soft version is the most realistic thing I've ever touched in my life. I can't even explain how happy my soft 5" from them makes me, and its my 9th packer, so I can compare to quite a few. I nearly cried when I held it up to my body and looked in the mirror. It literally feels like my own dick. I got the largest (which is also uncut which is why I got it) and it set me back about $70 which is why I don't recommend it for a FIRST TIME packer, but it's 100% worth it if you know you like to pack. The smaller ones they offer are less expensive as well, so they may be more reasonable for a first time packer.
I also prefer my packers to be above average sized and let me tell you, for some reason, the S Limpy is one of the harder ones for me to pack. The only thing harder to pack is my pack n' play freetom, and that's only because that one is a pack and PLAY. I have a harness that works well if I pack the S Limpy upwards, but I don't really use it outside of that harness, which unfortunately gets VERY smelly VERY quickly. Like after a day of wear the first time, I almost threw up when I took it off and the smell hit me. I don't know how the fabric reacts so badly to my natural smell down there. If you really don't want something as small as the MASHO or XS limpy, then I would also recommend the sailor, but be warned that it isn't very durable, and its a little more expensive. I liked it decently but I have better packers, which is why I don't use it much.
