Depending on your budget, a large unflared chance in medium firmness or a medium flared chance in medium firmness might be good. Bad dragon has regular sales every now and then, so you could probably cop one for around ~35% off.
A large bishop in medium firmness from exotic erotics would also be good.
And if you look in your own, I personally say to look for something in the ~7.5 inch circumference range.
