Hello, Thanks for writing to us. Vaginal pain and bleeding after first time sexual intercourse is quite common thing. It may be due to partial rupture or tough hymen, tight or narrow vagina, rough sex, dryness of vagina or less arousal etc. Urinary tract or vaginal infection should be ruled out by swab test and routine urine examination. If bleeding continues more than 3 days, I can suggest to undergo TVS scan to rule out other pathology like endometriosis, cervical polyp etc. When you will arouse or excite, the vaginal canal lengthens & expands so that your partner can enter his penis and you will produce vaginal lubrication (to prevent uncomfortable friction from thrusting). It is also possible that you were just nervous if it was first time sex which may cause your vaginal muscles to tighten, making penetration more difficult and painful. Steps to be done for easy and smooth sexual intercourse: 1) Next time, you must indulge in lots of foreplay to arouse yourself in top level to increase your vaginal lubrication before penetration. 2) You would be in more relaxed state and both of you will create a romantic environment so that you can focus and enjoy your sex. 3) It will also help if you add water-based lube (like KY gel or VAGISIL etc) to your vagina for easier penetration. Make it a part of preplay by having he lube you, then return the favor and ready to apply it on condom-covered erected penis right before he enters. 4) It s important that you must communicate to him what feels good and what doesn t. You can let him know what you need by saying like a little slower or harder or just like that and so on. 5) Also, you can try a woman-on-top position, which will put you in control of the depth and rhythm. Once you get used to the ins and outs of sex, it should be a lot more comfortable and fun. Hope, it helps for you. Good luck.
