OK, it's a very personal question so only answer if you feel comfortable, but charting has made me realise how little we manage it some months.
Pre-TTC we were weekend bonkers. We both work full time and tend to use weekday evenings for gym, seeing friends, work events, etc.
As fertile times don't always fall at weekends, we now make the effort on weekdays around ov time. But the amount we manage varies hugely, particularly as I travel for work sometimes. Since we have been trying we have done it between 1 and 8 times around the fertile period in a cycle (the one was the night before I went overseas for work for two weeks).
Although targetting the fertile time, we are still managing to have a lot of fun with it.
