Jamie has a son named William Ransom with Geneva Dunsany, who died during William's birth. Jamie also has two stepdaughters, Marsali MacKimmie Fraser and Joan MacKimmie, from his marriage to his second wife, Laoghaire MacKenzie.
Nonetheless, Jamie did have sexual relations with Laoghaire in a bid to make the marriage work but ultimately failed and so the couple separated. Additionally, it seems Jamie was acting of out duty to his new wife however past trauma meant Laoghaire was unable to reciprocate.
After the dust has settled, and with assistance from Ned Gowan, Jamie's marriage to Laoghaire is declared invalid – as Claire was clearly still alive – and he agrees to pay her a yearly fee and provide a dowry for each of her two daughters.

This one stings.

Claire Saves Jamie's Life by Giving Him a [NSFW] in Outlander Season 5, Episode 9. Forget CPR! So, this entire episode of Outlander basically revolved around an evil snake (Lord Voldemort, is that you?) biting Jamie's thigh, and it was all extremely dramatic and angsty so let's get right to it.
Claire gives him a beautiful, tender answer: she shares his regret, but regret is not enough. And together they make the decision to give the baby to Lucinda, a young mother who lost her own baby at birth, and has both love and milk in abundance.
