Well-rounded objection backing Times (5) I have tubby

and

Read all about technique America's adopting -"Read all about it" here! (4,5)
I have kama sutra

thanks

1) objection backing = but reversed = TUB
times = BY [multiplication]

[humbersloop]

thanks bibble, I'd got stuck on seeing t for Times

[bibblebub]

something along the lines that all reversed/about there are the components

technique = ART

america = AM. inside it = S.A. [sex appeal] inside here = UK

art U s am a K

(but a bit iffy)

[bibblebub]

(more than just a bit, in fact quite iffy)

[humbersloop]

cheers again - struggled to finish it and didn't enjoy it that much

[bibblebub]

it's the only way I can think of getting a K into the answer (i'm assuming that kama sutra must be the answer) but maybe someone else can come up with a simpler explanation

[humbersloop]

difficult for it to be anything else, the crossing letters are k?m? s?t?a and I'm pretty sure they're right

maybe just not a good clue

[bibblebub]

with all those letters it can't be anything else

[brantisaurus]

I think it's art (technique) usa mak[e] (variety, as in make of car) backwards
