How to get rid of trapped gas?

Last night my partner teased me a little, well alot actually, woke up this morning as horny as ever but his at work so I've told him what i want him to do to me tonight and ive already soaked through a pair of panties just thinking about it.

BUT ive got trapped wind i think, i feel bloated and it hurts to move sometimes, im afraid i wont enjoy it tonight.

How do i get rid of the discomfort quickly?
