I rolled a blunt with period blood on my fingers
Is that something you do often?
Yes, I do admire the effects of period blood
That feels very unsanitary and there may be sexually transmissible diseases with that blood and you may unknowingly pass on those diseases onto other people, and I feel like you really do not want that. So I suggest you stop doing that and be more sanitary next time.
I just don't feel comfortable having sex during my period, but rolling a blunt is a good idea. Besides, if I'm going to fuck up, I'm going to fuck up big.
I do not think it's healthy for you to think that you're going to fail big time. I hope you strive to be better and more successful, and you shouldn't do something that you're not comfortable with, but you should also not try to force something to people such as sharing a blunt with blood. I do hope you stop doing that.
