Thank you for your question. In the light of the question that you have asked, first of all I would like you to know that genital herpes is a Sti that is, sexually transmitted infection, and therefore if your partner was suffering from it then you may have acquired it while having sex with him. But there is an equal possibility that this problem may not be of herpes. In this regard I would suggest you to approach a doctor to know the actual problem. Regarding your query regarding symptoms I would like to bring to your knowledge that ulcer is a sign of herpes but it takes about 2 weeks for a person to have the symptoms of the problem. Since you had sex around two and a half year ago, there is a very less possibility that you have herpes. In some cases a patient may not have severe ulcers and therefore may not be able to notice it within 2 weeks. Only this case the ulcers may be a symptom of the problem that had been transmitted 2 years ago. As the possibility of the later case is very less I would like you to have this problem confirmed. There is also a possibility that these are the symptoms of other problems like HIV infection or syphilis. Till that time you may keep yourself aloof from any sexual intercourse as this problem is a Sti and may be spread to your partner. Hope this has answered your question, all the best.
