Hi, I am new here. I am so sure this has been asked before, and if there are good suggestions - just point me there. I can't seem to search for it successfully. OK - I have a husband and his penis is average if not on the small side. I have been with other guys before, and they were similiar, maybe a bit larger than he is, but not real big. We have an open marriage, and the issue I am having now is with my FWB (friend with benefits). He isn't overly long, but he is quite thick, at least for me. I have had one bladder infection since being with him, (we have been seeing each other for about 6 months), and the subsequent yeast infection brought on by the antibiotics used to cure it. It was the first bladder infection I have ever had. OUCH! Now everytime we have sex, it hurts upon penetration. It is kind of a shart burning pain that slowly gets better as we continue. It doesn't hurt after at all, although sometimes I bleed after - not sure where the blood is coming from (vagina or urethra), just a small amount. We have used condoms (latex and poly) and not used condoms (I am on other B.C.) used lube and not used lube (silicone and water based). Nothing seems to make a difference pain wise. I don't think i am tightening up, because the pain isn't like that (ie: having sex when I am not ready). Recently I tried to have sex with my hubby and that hurt in the same way! What is this? What do I need to do about it? FYI - this guy and I get together every other weekend and have sex from one to three, maybe four times. Frequency doesn't seem to make the pain better or worse. I hope someone can give me some help... he feels badly and I am tired of hurting. Thanks!
