You can absolutely discuss your sexual fantasies here, as long as the posts abide by our forum rules, these are some of the rules to bear in mind:
The Lovehoney Forum is not a place for arranging hook-ups, sex chat, cyber sex or other personal solicitations. It is not a place to post links to pornography or erotica, or a place for seeking out material you may use to masturbate. Similarly, do not post about sex acts in progress, this is strictly prohibited.
Do not use offensive, unnecessarily graphic/erotic, derogatory or inappropriate language
Do not post erotica or graphic fantasies learn what erotica is here
Do not single out minority groups (including races, ethnicities, sexualities or gender identities) as arousing you or being part of your fantasy. Real life is not like pornography and real people deserve more respect than being reduced to fantasy fulfilment
This thread is probably the best place to start 
What's your fantasy?
