My vagina is itchy and when my bf tried to enter me it feels as if I am so dry and swollen. There is no puss or discharge. I'm not sure what to do.?

Could be "yeast" Sounds like monilial vaginitis-annoying not serious exam to confirm would be best. Over the counter anti yeast medicine may help.
YOU MAY WANT TO. Spend more time hanging out and getting to know each other in a non penetration type relationship for a few days. It sounds like you have an inflammatory process that needs to be seen by your gyn. Once symptoms clear, you should be ok!
See your gyn. It could be a number of things and better ti b get the diagnosis or an expert opinion than to self treat, as otc meds for the wrong condition could make it worse.
