Do you think sex is more passionate if you have him wait longer than usual?

Me and husband before I got pregnant were going at it like bunny rabbit's. like 2-3 times a day. Since I got pregnant it turned into 1time a day and in the second trimester. And at the beginning on the third trimester it turned into 2 times a week....now its down to MAYBE once a week. Well me and my husband hadn't had sex in like a week and a half...he didn't even seem interested in sex. But last night he all of a sudden started kissing me very passionately... He usually doesn't kiss me with tongue he just gives me pecks. And he got on top of me and started grinding... He never done that before either! He usually doesn't put in all this effort. And since I've been pregnant he stopped playing with my boobs...well last night he couldn't stop touching them! I'm sorry if its TMI but I'm just so happy and pleased and surprised by my man! If he is like this when he waits this long to have sex then I'll have him "wait for it" more often!" We just had been stuck in a rut and he refuses to explore with new positions. But I tell you what ladies, its worth it sometimes to make him wait until he can't hold it in any longer ;)
