Hypothetically speaking if I a 18 year old man paid a 48 year old woman to have sex with me and I wear a condom and we both consented to it is that morally wrong or is it morally okay?

In my opinion I think it’s morally okay if a 18 year old man pays a 48 year old woman to have sex with him as long as they are both consenting to it. Because what they’re doing is completely harmless.
