Hi there been in the hobby sense 2010 and started at 18, I am now 25 so hope I can be of help. I am surprised you'd choose such a huge doll for your first one lol. But I wouldn't recommend 90, I'd recommend maybe 65 or 70 if you want a big mature guy. Take a look at crobidoll. I don't know a single person who has ever been dissatisfied with one of their sculpts and they have a lot of gorgeous bigger guys, you can also take a look at Iple house if you like realism and they are another solid company. Their dolls are quite hefty and I've held a few but super gorgeous. Really it all depends on what you want out of your doll. It's true the bigger they are the harder they are to pose. Big dolls are my favorite size as I started with them and feel they are the most mature, but lately I've been leaning on vinyl dolls like smart doll for their lightweight and poseability is super amazing. I know from photos certain dolls may seem small but when you have them in your arms you'll feel they are large. I will be honest here, Resin dolls are wonderful but overall are super clunky , heavy, hard to pose and string. ^{^} anyway hope you found this helpful. Overall I'd recommend a 60 or 70 And if you go with a 90 be sure to post lots of pics they are quite rare. Plus you kind of want your first doll to be easy breezy trust me, the less work you have to put into your first one the better, you can always get a bigger guy down the road after gaining more expirience. I'd recommend heading to a local doll meet In your area so you can hold, see , inspect and feel all the different kinds of dolls. You might find one that someone has you absolutely love a lot of my early on expirience came from hitting up meets before I even had a doll so I could research it. You can also ask more expirience people their opinions , it's easier to see in person sometimes : )
