When he tells you " let's star trying "

Alejandrina
Hi ladies . I have some concerns . I'm 22 my fiancé is 20. For the past two months he told me he wants to " TTC  ". So since he told me that I've boosted my love/sex game ! But every time we make love he does the pull out method. I've never asked why he does that . Or just asking him if he not ready ! I don't want to feel more disappointing . Throw me some advice plz .!
