Because people aren't just blow up dolls, perhaps it isn't totally a good excuse.
But...I surely understand it.
Having warm lips to kiss, a hot body to embrace, and a flush of pleasure can be a wonderful tonic.
If you do this, just make sure you are clear that this is just for mutual fun, "no strings attached" (so you don't break someone's heart), and try to avoid STIs.
After enough time goes by for healing, I hope you find your new true love and regain your joy.
Hugs!
