NSFW: Bleeding after masturbation since starting T

Yeah, basically what the title says.

Also this is literally my first Reddit post ever and I cannot find the NSFW tag for the life of me. Please let me know how to add it or if I need to delete this post :)

I'm a 17YO FTM, and have been on testosterone gel for roughly a month about now. Since September 2025 (if I recall correctly) I have been on menstrual blockers (lynestrenol) to stop my menstrual cycle. Dunno if that is relevant, thought I'd mention it anyway. I still take menstrual blockers now because the testosterone by itself isn't enough to stop my menstrual cycle at this stage.

Now here's the thing. Every time I masturbate I bleed a bit. It's mostly blood that's kinda mixed with what usually comes out during an orgasm. This hasn't happened before and has only started since I began HRT. It doesn't hurt either. It's just kinda there.

Is this something I should be concerned about? I have a check-up appointment with my doctor in a few weeks, should I bring it up then? Or could it be something urgent that I need to contact my GP about?

Thanks in advance 🙏
