How to, ahem, help him DTD more in a month? Any real aphrodisiacs?!?

[Oldermum6]

TTC at the moment, and DH can really only do it twice around ovulation. He’s probably naturally a once-a-week person! So getting him to dtd every day is out!

I want to try and DTD once every two days from the day after tomorrow so we’ve got a better chance this month (so a total five times in 10 days).

Is there any natural aphrodisiac that will help??? Or any food / drink to avoid / anything he could eat / or more exercise?

Me and DH are planning to TTC from this coming cycle. We've invested in lots of new lingerie, I think it's normal to find it a bit of a challenge to have sex on demand rather than spontaneously
