So this is a self defense kit thingy?
I don't know where you live, but if it is a relatively rough area, the thing could be a genuine gift, given out of concern. Being trans can be dangerous. Some people's mind can simply not step out of the binary male/female mindset, and everything that challenges that can be met with aggression at times. Perhaps the gift was given out of concern, regardless of your gender, but given because you are a minority (trans) and thus at risk. I doubt there are 'gentlemen in distress' kits to buy.
When in doubt, just talk to the gift givers. They may have given it out of concern, bought it without thinking much of it, or given it out of malice (the latter seems less likely). Only communication can create understanding, and with understanding can come the prevention of future mishaps.
