Please forgive me butting ( no pun ) in but electroglide and such 'oils' are much better than either KY or vaseline , vaseline is rather sticky and KY can be absorbed and dry out , also plug type - glass are excellent for long term use as are to some degree metal - surgical steel - plastic/rubber plugs are ok for short term use ,upto maybe 2 days maximum . As a long time user of plugs ( i now wear one permenantly and have for almost a year now ) i have found the need for any lubrication redundant as my anal cavity and ring seem to be a perfect fit for my anal plug carefull removal and insertion is all that is required for those breaks for enamas and rare use of toilet and cleaning .Again please forgive me for interupting you A/all
