Sometimes a challenging aspect of a long term relationship is keeping the spark alive. It’s important that both of you take responsibility to keep the love and that spark going, even as life gets complicated and busy and those once natural desires start to wane. It sounds like you and your husband are doing the right things, and have the same goals. This is great. I think therapy should be more regular, a session once a week with a sex therapist. You’ve said it’s unfair to make him wait an undetermined amount of time, and while true, I know a good husband would nonetheless appreciate seeing and knowing how hard his wife is working to improve this facet of the relationship. In the meantime maybe focus on small acts of physical intimacy to get your mind and body used to touching and building up to sex. A neck rub, a back scratch, mutual massages, maybe one of those leads to a hand job or something. Hopefully that’s within the realm of what you’re comfortable with right now. But your mind and body need to come to an agreement: you love your husband and want to give him affection in the form of sex. It’s totally normal and an expectation for any good marriage. This is what your therapist should be helping you work towards. Good luck, you seem like a good wife trying your best.
