Good thinking, not too old fashioned and I endorse your thoughts. But "No sex please! Im single" also includes the numerous singles who are divorcees as well, who,for whatever reasons are unfortunate or fortunate in some cases and therefore single by virtue of that. Some traumatised by their marriage and happy to get out of it. Should we prevent them from having sex with someone they want to? I am sure there are quite a few of them who do not want to get into another marriage for the fear of yet another breakdown and therefore prefer to stay single. Why cant they enjoy sex with someone whom they seem to get along with or without a committment?. Where has marriage led them anyway? and why not sex if the two decide and love one another and provide each other with their individual needs??. I advocate strongly in their favour and feel that the biological needs in this case is purely upto the individuals concerned given his or her situation.
