You’re too penis-centric in your thinking.I just worry that she is going without because of me.
At last count there were 4,372,901 other pleasurable and even orgasmic techniques and activities that do not require an erect penis.
If you’re that concerned about her pleasure, then start exploring and experimenting with ways to please her without pumping her out to other men if she doesn’t want to get with other dudes.
IMHO you’re simply shirking and pawning off YOUR responsibilities.
If she wants to get with other men, she has certainly shown that she has the ways and means to get them just fine on her own.
