I usually sit in his lap and kiss him. Like another pp as long as the kiss lasts longer then 10 sec he gets the hint.
Disclaimer: we don't always make it to the bed.
DH usually just starts groping me. Or he asks if ill put the dog in his crate. (The dog always wants to join and it gets weird, so we lock him up. Lol)
The other day I yelled " I'm having fertility signs, put it in me now" at him from the living room
Otherwise I jump him or I just don't stop him when he start The Grope
ETA- you know, your SO doesn't have to be in bed to have sex with you
Many a good sex life has been ruined by this thing. Proceed with caution - it will only be endearing for a few months (if that) and then it will start to feel like sex is for one reason and one reason only. And then the implosion.
