Std? Have you ever experienced this?

Hey girls! I haven’t been sexually active in 4 months and last time I tried, the guy couldn’t penetrate because I wasn’t wet enough. I’ve been having a hard time getting wet since December... In addition to this, I have a small white lump right above my clit, and it hurts when I touch it and when I wipe after having gone to the bathroom. Do any of you have an idea of what it could be or have you experienced this?

Thank you!
