Nothing new.
Where is the most daring place you have had sex with your partner?
Get anal - I don't find the anal ring gives me a lot of stimulation and not very exciting, but the couple of times I've been successfully fucked were mind blowing experiences, also enjoy receiving ass play, especially when getting a blowjob, so that's an easy answer for me.
Tie someone up and fuck their mouth, or be tied up and have your mouth fucked? (Can be a guy or girl doing the mouth fucking/grinding - please specify which gender you wish it were with you 😎)
