Masturbating with EMLA?

Has anyone tried to masturbating with EMLA? If so, how did it go vs when you had sex with it? I last about 30 seconds masturbating without EMLA and having sex even less, about 10-20 seconds. I tried masturbating with EMLA recently and it did increase my duration a fair bit, to about 2-3 minutes. But won’t that mean I’ll only last about 1-2 minutes having sex with it? Just pretty anxious as I’m seeing a girl for the first time soon and want to get it right haha. Keen to hear other people’s experiences
