I'm an 18 year one lesbian, recently every time me and my partner have manual sex or when we have mutual masturbation- where she rubs my vulva. At the end of this whole sexual activity, my clitoral glans, labia minora and vagina walls swell up. There was once it was really painful when I sat or bathe especially when I wash it with feminine hygeine wash. I like this whole sexual activity but I don't want my vagina to swell everything we do such a thing it's quite a hassle cause it feels quite uncomfortable. Please tell me what to do. Thank you, any advice would be greatly appreciated.
