Tried it - not practical beyond 10 minutes, the leakage will force you to break apart and clean up. Dried - crusty stuff congealing in short haired areas is prickly-pinchy-painful too. If you manage to get things settled and snugged together, one of two things invariably happens...
She will at some point dream of something, move - a woman's internals are strong, and will eventually push a soft penis free. The second thing, and this happened to me and we NIXED the idea after that and fetching a baggie of ice...
My partner was smoker, given to a light cough here and there in her sleep. Well she coughed...
I screamed.
