Tell you something my Mrs does that really fucks me off. She might start grabbing my dick through my kecks and stuff when she knows there is no chance of anything happening because my lads' upstairs or something.
But if he goes out to play all of a sudden there's a desperate need to go the shop or she's suddenly overcome with tiredness and needs to go to sleep or there's some other shite excuse not to do anything.
Same happens with me. I'll get really frustrated over several weeks having my requests knocked back. Tiredness, headache, stomach ache, just don't feel like it, maybe tomorrow (to which I usually respond that I'll put it in my diary to confirm the appointment), etc.
Then I come home from work and she'll start the sort of stuff your saying, really working me up for it. Time comes and "no, not tonight, I'm too tired, I've got a headache, etc.". If I complain enough over a few weeks she'll finally give in, then afterwards will say "happy now" jokingly. No, not really, because I've got another 3-4 week wait now for next time".
Even when we were trying for kids she would do this, then wonder why she wasn't getting pregnant. Well, there is a good reason for that my dear....
And all this literally started the night we got married. So if you're not married, don't do it, it is the end.
