Which is better: ky intense or durex play utopia?

me and my boyfriend have been intimate for quite some time and I have yet to orgasm. I'm hoping one of these gels will help me do so. I'm looking for a good gel that will do the job and wont be too expensive. 2 gels that seem popular are ky intense and durex play utopia. I have never tried these products and I don't want to waste my money on something that won't work or will burn. which one is better? And, if there are any other good arousal gels that arent too expensive I'll look into those also. I'm completely open to any options. thanks!
