Advise please!

Ok so my boyfriend has mentioned that he doesn't like to go down on me after we do it with condoms

He claims that I have a rubbery smell and taste down there and he doesnt like it 😢

It has notbing to do with my natural scent, its just the condom since he has gone down on me before without the condom residue and has even told me he loves my taste but that I dont smell bad down there

What can I do to avoid the smell?

He wants to be able to make me orgasm mulitiple times since hes insecure about his size (6in) even though hes the only ive been with and have told him multiple times he is not small!

He still thinks he is not enough for me and we have read that oral could help me with that

Has anyone else had this problem? Could latex free condoms help? Idk anything would help!!
