How do i go about this?

Ladies, I'm 9 weeks pregnant and my libido shot through the roof the past month... Only my guy is exhausted from 2 jobs that he barley has any energy.. and when he does, it's just a quick "get the nut" and go to sleep round. I want more. Ive done the wake him up with the bj, foreplay, tease, lingerie, whatever. I've also verbally stated "hey I need more sex or I'm getting a toy".

He's completely against me getting a toy, he won't say why but I'm guessing it because he isn't very well endowed. An ego thing. I don't want a tiny vibrator, I need penetration lol I feel like a raging, thrusting horomone monster I'm always so frisky.

Anyway, I'm usually straight forward with things so if I ask the wrong way he may be offended... How would you go about asking your man about bringing a toy/toys into the sex life. Like I want to try some different things I need to spice it up..or I'm gonna get bored and buy who knows what and things will get out of control.. I understand he's tired but he use to want me alllll the time. Now I'm starting to feel like I'm unattractive and he doesn't fancy me or my needs. Im not discrediting his lack of energy, I'm willing to take care of it myself.. only his ego ..Ugh! Help me out sis!
