I do speak to him about it and he understands but i cantbhelp feeling guilty because he has a high sex drive and we used to have sex 2 to 3 times a day and now i could easily go 2 weeks and feel no urges or horniness at all .... once it has been initiated and a few minutes in then im fine ! ( hes great in bed ) and the enjoyment kicks in but i just miss not having the excitment building up to it.
