These days I rarely wank straight afterwards though that can work with women who are into that. I always do at some point before next having sex though because sex is pretty infrequent at the moment.
The irritating thing is that i'd be happily give up masturbation if sex happened every few days. I'd just stop after ten minutes or so and hopefully, within the week i'd be shooting a load into her. I cum most days so it's not like i'm not producing the stuff.
Unfortunately ten minutes in is the point she's really getting into it and starts begging for me to cum inside her. At this point I find it pretty hard to say I don't want to try so we carry on until i'm past the point where it's probably my fitness levels holding me back. At this point she's "getting sore" and we stop.
I think she's rather too focused on me cumming, as was my last GF. The one time I just stopped saying "I'm unlikely to cum and I don't want to just keep going until you're sore" she seemed very hurt and talked about "trying again soon", which hasn't happened yet. It's been two whole weeks...
To be honest I think the problem is, she just doesn't like cock as much as some women, or she used to. I prefer the type who are so into fucking they couldn't care less if you cum or not.
It's possible my current situation complicates things further. I was with a highly sexed woman for 12 years, ten of them married, we went from having a fantastic to pretty good sex life (still a couple of times a week at the end) and got divorced eight years ago. Since then i've fucked a lot of women and been in several relationships, some total fuckfests and some we're i've been almost celibate.
Now, weirdly my 'girlfriend' is my ex wife. Things are awkward, the kids are eight years older, we live in much smaller houses (her fault, she made us sell the big house 8 years ago...) and sex just doesn't happen very often, we don't live together all week and she won't do it if the kids are in and awake. She goes to bed earlier than the kids... When it does it's pretty good other than the not cumming thing but there are complications from the other relationships we've both been in. I did get a massive ego boost when she said she'd forgotten how big I was and described me as twice the size of her ex when we first got back together though
