Recently learned husband uses testosterone cream on abdomen, and i had been exposed to it many times (during sex) without knowing. my increased libido was fun, but is this unhealthy for me?

Probably not!: You maybe getting a minimal amount of testosterone into your body transdermaly and that may increase your libido! this could be harmless especially if you do not show any possible signs of musculinisation in your body! (increase hair on your body, changes in voice, more muscular development, etc.) this is unlikely especially if your husband uses the testosterone cream hours before intimacy!

Could be if pregnant: Monitor for facial hair growth, your husband needs to wear a t-shirt and try to avoid esposing your to areas where he applied testosterone. There is medicine for women with low libido due to low levels of estrogen and testosterone Estratest (esterified estrogens and methylestosterone) would be an example. You would need to see your doctor for a rx. If appropriate.

Possibly: The package insert of testosteron creams usually warn about the unwanted transfer of testosterone to the spouse/children. To avoid this, an undershirt may be worn as protections. If your husband uses the cream once a day, then he may apply the product in the morning. As for you, the best option is for you to have your baseline testosterone levels checked. Testost. Rx will be off-label.
