ITS ALL OFFENSIVE-OBVIOUSLY EVERYDAY VIEWING FOR SOME CRETIN ? BUT NOTHING TO DO WITH THE QUESTION

In answer to your question guys, you should be ok
Its quite normal to see two men walking around arm in arm - but not male and female (not sugesting that you would)
I would sugest you keep your private life private,I do not think you would be able to sponsor your partner but as he is from the Uk he can get a 6 month visit visa issued in the Uk
before you come which would give you time to see how you both felt about qatar
