All things considered, there aren't any bad things about being big.
For me, always being careful during sex.
You always have to be considerate of a new female partner until you know how deep you can go. I'm lucky that my current gf takes all of me, but she helped things along when she started fucking regularly checking out her pussy with various dildos to find out how many inches she could tolerate. Length is less of a problem with anal because you have the freedom to angle your cock differently. I always end up balls deep in my two buddies. I suspect that thickness can be more of a scary challenge because there are limits to which you can stretch a partner unless they're seriously into pain. I'm glad I'm not a beer canLength. Can't thrust the way I sometimes want to without hitting the cervix. I mean you have to be careful and controlled. On the other hand, maybe I have lousy technique.
